7 Steps To Create Your Own Eco-Project

Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at 7 Steps To Create Your Own Eco-Project. As global warming rises steadily, people have started realizing the importance of sustainable, green, and clean living. People that once considered global warming to be a hoax are now actively searching for eco-friendly ideas and how to be environmentally friendly. The reasons behind this change can be attributed to the numerous catastrophic changes that are taking place around the world due to global warming. This is also one of the reasons that colleges and universities are taking such a keen interest in making sure all students are well versed when it comes to climate change. Projects on how to be environmentally friendly and researches on global warming are highly encouraged in academia nowadays. A paper based on the effects of global warming, eco-friendly ideas, or environmental tips is much more likely to be successful than other papers because this topic is relevant to the world today. To help you get started on the best eco-project or paper, we’ve made a list of some excellent eco-friendly ideas and environmental tips! So let's get started with the 7 Steps To Create Your Own Eco-Project.

7 Steps To Create Your Own Eco-Project

 Conserve Energy

• Conserving energy is an excellent eco-friendly idea for creating a sustainable environment. The steps to do this are incredibly simple; all you have to do is be more cognizant of the electricity you use.

• Switch off the extra lights and fans you're not using, and don't leave electronics plugged in. Simple measures such as these can cause a drastic change in the percentage of energy you conserve.
• You will not only do your part in preventing global warming but will also notice a considerable reduction in your electricity bill! A win-win situation with no drawbacks whatsoever.
• You can check online to find more creative, eco-friendly ideas on how to be environmentally friendly and conserve energy.

Renewable Energy Is The New Way To Go

• There has been considerable research done on how beneficial renewable energy is for the environment. Students who are considering doing a paper on renewable energy have a plethora of options to choose from.
• New forms of renewable energy and eco-friendly ideas are being discovered almost every other day. Hence, there is loads of information available online to help you write an excellent paper.
• However, if you do not reword the information you picked up online correctly, you could get penalized for plagiarism. To ensure that your paper is plagiarism-free, run it through a free online plagiarism checker such as PapersOwl before turning it in.
• If you have a capstone project on the subject, then you can refer to one of the numerous free helpful websites that guide you on how to write a capstone paper easily.

Use Eco-Friendly Technology

• Most new technologies being introduced in the market have some measures of eco-friendliness and energy conservation incorporated in them.
• The newer LED and compact fluorescent lightbulbs produce much less carbon dioxide as compared to the older incandescent bulbs.
• Most modern refrigerators are CFC free and Split system air conditioners conserve much more energy compared to their older counterparts. You can check online to know more about modern, eco-friendly ideas and how to be environmentally friendly by using the latest technology.

 Reduce, Reuse, and Recycle

• This is a simple and catchy slogan that can lead to numerous, innovative eco-friendly ideas and environmental tips!
• Reduce unnecessary usage of things, reuse whatever you can, and always recycle! Students can use recycled paper in classes, metal straws, and lunchboxes instead of single-use straws and plastic lunch bags.
• Simple measures such as these can lead to a much cleaner and greener environment.

Insulate Your House

• Insulating your house makes it much easier to cool it down during the summers and heat it during the winters.
• Without insulation, not only will you have a hard time keeping the temperature inside your house stable and comfortable, but you will also be spending a large amount of money on heating and air conditioners.
• House insulation is a one-time investment that you can benefit from over numerous years. It is one of the simpler eco-friendly ideas and environmental tips that you can implement and benefit from as well.

Reduce Waste

• This goes without saying. Reducing waste in your house, whether through recycling or composting, can help you tremendously with keeping the environment clean.
• By waste, we don’t just mean just plastics, even wasted food is terrible for the environment as it produces tons of carbon dioxide in large landfills.

• Reducing waste is easy, free, and helps reduce your carbon footprint as well. You can check online for different ways to reduce waste and compost using leftover food!

Plant Trees

• Deforestation is one of the leading causes of global warming. Each year numerous forests and wooded areas are destroyed either by timber companies or due to urbanization.
• A single tree can absorb 1 ton of carbon dioxide in just 40 years. For this reason, one of the best things you can do for the environment is to plant a tree.
• Students can even get together and organize tree-planting drives for the community while discussing how to write a capstone paper. Environmental tips and eco-friendly ideas on how to be environmentally friendly can be spread during such campaigns to raise awareness about the issue.

Conclusion

• Slowly but steadily, people realize the importance of being eco-friendly. Numerous online publications have well-sited, well-researched papers that back the importance of creating a sustainable and clean environment. Being conscious of our environment is the only way we can prevent global warming and reverse some of its effects.

It is the detailed tutorial on 7 Steps To Create Your Own Eco-Project if you have any question about it ask in comments. Thanks for reading.

Introduction to Structures in C#

Hello friends, I hope you all are doing great. In today's tutorial, we will have a detailed Introduction to Structures in C#. It's our 17th tutorial in C# series. Structures are quite similar to classes but have few differences as well, which we will discuss today. We have discussed C# Classes in 13th lecture, so you must read it once as we will use that knowledge in today's lecture as well. So, let's get started with Introduction to Structures in C#:

Introduction to Structures in C#

• Structure in C# is a value type data type, created by using keyword struct, and can have fields, methods, properties, operators etc. just as in C# Classes.
• Main difference between C# Class & Structure is that C# Class is a Reference Type Date type while C# Struct is a Value Type Data type.

• Let's have a look at the syntax of C# Structure:

• You can see in above figure, that we have created a struct in C# named StudentsData and it has two private fields in it i.e. ID and Name.
• This structure declaration is quite similar to that of C# class and the only difference is that we have used struct keyword here, instead of class keyword.
• So, now let's add a C# Method in this structure and then invoke it from Main Function, shown in below figure:

• So, you can see in above figure that we have invoked structure in the same way as we invoked C# Class.
• We have first created a reference variable for C# structure and then invoked the Structure Method. ( as we did for C# Class )
• We can't inherit a structure from a Parent Class or any other struct but we can inherit a class from a structure.
• Both Structs & Classes can inherit from an Interface. ( which we will study in next lecture)
• C# Data Types i.e. int, float, double are examples of Struct in C#.
• Structs are stored on Stack while we use Heap for storing C# Classes.
• Let's have a look at Struct Constructor, which is slightly different than Class Constructor:

Struct Constructor in C#

• Structures in C# can't have destructors, if you add a destructor in struct, then compiler will generate an error.
• Although you can create a Constructor in C# Struct but make sure it has some parameters in its definition.
• A parameter-less constructor is not allowed in Structures but you can overload Struct Constructors.

So, that was all about Structures in C# and you must have noticed that they are just Value Type version of C# Classes, which are actually Reference Type. In the next lecture, we will have a look at Interface in C#. Till then take care & have fun !!! :)

Introduction to Polymorphism in C#

Hello friends, I hope you all are having fun. In today's tutorial, we will have a look at Introduction to Polymorphism in C#. It's our 16th tutorial in C# series and polymorphism is considered as a main pillar of object oriented programming. In our previous tutorial, we have seen a detailed Introduction to Inheritance in C# and along with it, we have also discussed How to hide a Method in Parent Class, if the same method exists in Child class. This Method Hiding is actually the basis of Polymorphism, so let's discuss it out in detail:

Introduction to Polymorphism in C#

• Polymorphism in C# enables the user to invoke a Child Class Method & override the Parent Class Method, using a Parent Class Reference variable.

• In our previous lecture on Inheritance, we have also discussed method hiding and our last code is shown in below figure:

• In the above code, you can see that we have used method hiding by using new keyword with ChildClass Method.
• So, now instead of hiding the method let's override it and have a look at the results:

• In the above figure, you can see that I have used virtual keyword with Parent Class Method.
• Moreover, instead of new keyword, I have used override keyword with Child Class Method.
• I have used the same reference variables as I did for Method Hiding code, but here in the third case, the child class method is called.
• So, in Polymorphism, if the Child Class is involved in reference variable, then it will always override the Parent Class Method and will use the Child Class Method.
• So, we can say that if we want to completely override any function in Parent Class, then we need to add virtual keyword in its definition.
• This virtual Parent Class Method will always get override by any Base Class Method, which has the same name and has override keyword in its definition.
• But if we want to invoke the virtual Parent Class Method, then we have to use Parent Class reference variable.
• So, this third variable PC2 is the main difference between Method Hiding & Method Overriding (Polymorphism).

So, that was all about Polymorphism in C# and if you have got the Method Hiding then it won't be much of an issue for you. In the next lecture, we will have a look at Introduction to Structures in C#. Till then take care & have fun !!! :)

Introduction to Inheritance in C#

Hello friends, I hope you all are having fun. In today's tutorial, we will have a detailed Introduction to Inheritance in C#. It's our 15th tutorial in C# series and again an important concept in Object Oriented Programming, as it helps in code optimization. In our previous tutorial, we have discuss namespaces in C# and that was the last storage item in C#. Today, we are dealing with entirely different entity, which is inheritance. So, let's discuss it in detail:

Introduction to Inheritance in C#

• Inheritance in C# is used to create a relation between two classes. In simple words, derived / child class is inherited from base / parent class and will automatically have all its members as its own. Inheritance is denoted by ( : ).

• Mostly in projects, there are few functions which we have to use a lot throughout the project, so we can place such functions in any parent class and then which class needs those functions, we can simply inherit it from that parent class.
• Here's the syntax for inheritance, where ChildClass is Inherited from ParentClass, so ChildClass can use all functions and fields of ParentClass:

• When we create a new instance of any child class, then parent class constructor executes first and then child class constructor executes.
• So, in below figure, I have created two classes, ChildClass is inherited from ParentClass and I have also created their Constructors.
• Mow in the Main function, I have created a new instance of ChildClass and you can see in the Console that first Parent Constructor Called & then Child Constructor Called.

• Suppose, you are designing a software for college class, where students have few same subjects but some different subjects.
• Let's say, Engineering students study Physics & Chemistry while Medical students study Biology but they all have to study Mathematics & English.
• So, I have created one Parent Class with name MainSubjects, which has the compulsory subjects in it.
• Then I have created two Derived Class named MedicalSubjects & EnggSubjects and I have derived both of them from Main Subjects, so they can use both Maths & English fields.

• You can see inheritance in above figure, in the definition of class we have MedicalSubjects : MainSubjects, so MedicalSubjects is inherited from MainSubjects.
• In the Main code, I have created new instance of MedicalSubjects & then updated score for English, which is actually in MainSubjects, and it updated correctly.
• So, I can use all members of parent class in derived class.
• The benefit of Inheritance is that, it allows user to reuse old code without writing it again, so it saves time and reduce errors.
• C# allows single class inheritance i.e. we can't derive class A from two different classes at the same time.
• C# allows multiple Interface inheritance, which we will study later in detail.

Now I hope you have understood How to use Inheritance in C#, so now we are ready to discuss a similar concept called Method Hiding, it's related to Inheritance so let's have a look at it.

Method Hiding in C#

• Method Hiding in C# is a simple technique, where we declare two methods with the same name, one in Child Class & other one in Parent Class and the Child method will hide the parent Method, if called from Child Class Reference Variable.
• We need to use new Keyword with the child class Method, which will hide the old Parent class method.
• In our previous part, we have seen How to use Inheritance and have created Parent & Child class.
• Now, let's create two Methods with the same name, one in ParentClass & one in ChildClass, as shown in below figure:

• You can see in above figure, that I have created a Method PrintMsg() in both ParentClass & ChildClass.
• In the Main Function, I have created 3 reference variables, which are:
  • PC is a ParentClass variable, pointing to ParentClass Object.
  • CC is a ChildClass variable, pointing to ChildClass Object.
  • PC2 is a ParentClass variable, pointing to ChildClass Object.
• You must be wondering about the third variable, yeah we can do that as we can use all members of ParentClass in ChildClass but we can't do the opposite.
• Moreover, when we called the PrintMsg() Function from 2nd variable, which is a ChildClass variable, then it has executed the Function in ChildClass, which has new Keyword in its definition.
• So, the second variable has completely ignored (hide) the method in ParentClass and simply used the new method in ChildClass and it's called Method Hiding.

So, that was all about Inheritance in C#, which is quite simple concept but really effective in complex projects. It is considered as a pillar of Object Oriented Programming. In the next lecture, we will have a look at Polymorphism in C#. Till then, take care & have fun !!! :)

Introduction to Namespaces in C#

Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to Namespaces in C#. Namespaces are considered as libraries in C#. If you have worked on any other programming language then you must be aware of the term library which contains all classes & methods etc. In C#, this functionality is performed by namespaces. In 12th tutorial, we have seen Introduction to Methods and in 13th part, we have seen Classes in C#. Methods are simple storage units and stores code only, Classes are slightly bigger storage units and can store methods. Now Namespaces are giant storage units, which can save anything in them i.e. classes, methods, namespaces etc. So, let's have a look at them in detail:

Introduction to Namespaces in C#

• Namespaces are giant code storage units, can be referred as libraries in C#, and are used for optimization & orientation of the code.
• Namespaces are included in the project with the help of using directive at the top.

• If you look at our previous codes, then you will find using Systems; at the top of your code, basically this Systems is a namespace and with the help of using directive, we have included it in our project.
• Console, which we use for printing our data, is a member of this System Namespace.
• Our whole project is also placed between { } brackets of namespace TEPProject.

Why we need namespaces ?

• Using Namespace, we can organize the code pretty well, it doesn't have much impact in simple projects but in complex projects, you can't ignore namespaces.
• Throughout our course, we have discussed classroom data and in C# Classes lecture, I have asked you to get data of all classes of a school and now in namespace case, think of data coming from all schools of British School System.
• So, in bigger projects, there's always a need to make different teams, which will be working on separate code departments.
• In such cases, each team can create project with its own namespace and at the end you can use all those namespaces in your Main code and can get access to its functions etc. without disturbing each other's code.

Creating Namespaces in C#

• So, now let's create two namespaces in our project for two different schools, named as SchoolA & SchoolB, as shown in below figure:

• In above figure, you can see our first namespace structure is: Namespace SchoolA > Class TeamA > Method printSchoolName.
• Our second namespace structure is: Namespace SchoolB > Class TeamB > Method printSchoolName.
• Now in my Main function, which is in TEPProject Namespace, I am calling both of these printSchoolName Method.
• In order to invoke the method in first namespace, I have used dot operator and the sequence is SchoolA.TeamA.printSchoolName();
• For the second namespace, I have placed using SchoolB; at the top of the code and now we can call TeamB class directly and that's why I have used TeamB.printSchoolName(); to invoke method in second namespace.
• So, we can use namespaces using these two ways and I prefer the second one as it makes the code smooth, we don't need to write SchoolB every time.

Create Project for Namespaces in C#

• Now you got the idea of what are namespaces and how to use them in C#.
• So now it's time to create separate projects for these two namespaces and you will see our code will become clear & simple.
• Right click on your Project's Name in Solution Explorer and then click on Add and then click on New Item, as shown in below figure:

• When you click on New Item, a new window will open and here you need to select C# class, as shown in below figure:

• I have given it a name SchoolA.cs and then click Add Button.
• Similarly, I have created a new project for second namespace SchoolB.cs and now my Solution Explorer is shown in below figure:

• Both of my projects' codes and Main file code are shown in below figure:

• Now you can see in the above figure that our codes are now quite simple & clear and we have created separate files for our new namespaces.
• C# Classes created in separated files and namespaces are now accessible in our Main Function.

So, that was all about Namespaces in C#, I hope you have understood the main idea. In our next tutorial, we will have a look at Inheritance in C#. Till then take care and have fun !!! :)

Introduction to Classes in C#

Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to Classes in C#. It's my 13th tutorial in C# series and now we are ready to understand this slightly complex subject in C#. In our previous tutorial, we have seen Introduction to Methods in C# which are used for organizing the code and we can add some code in separate methods to make the Main method simple. Classes are slightly bigger storage capacities than methods. Methods can store code, classes can store methods. So, let's discuss classes in detail:

Introduction to Classes in C#

• Classes in C# are referred as storage units for different methods, fields, objects etc. and are used for organizing the code.
• In our previous lessons in C#, we have always taken an example of a classroom but what if we have to create a software for an entire school system.

• In that case, we can create separate teams, dealing with each classroom, so you can think of that classroom as a class in C#.
• Our Main method is in class Program, Let's create a new class for OLevel classroom students:

• so, in the above figure, you can see that I have created a new class named OLevel and this class has 3 members, named as:
  • First one is field/variable named: FirstName.
  • Second one is field/variable named: SecondName.
  • Third one is method named: printStudentName.
• So, we have 3 members in our newly created class and all these members are instance members as they don't have static keyword in their statement.
• So, in order to call this OLevel method in Main method, we have created a new instance of OLevel class, as we did in our previous lecture on methods in C#.
• After that using this new instance of OLevel class, we have invoked the printStudentName method using dot operator.
• When we run our code, we have the Full Name : TEP C#, as given in the code.
• You can also use Constructors & Destructors in C#, but they are not necessary to use, as we haven't used the constructor but our code worked fine.
• So, let's have a look at what are these terms one by one:

C# Class Constructors

• C# Class Constructor is a simple method / function, which gets executed automatically whenever the new instance of class is created.
• It must have the same name as the class itself and it won't have a return type and the access modifier is public.
• Constructors are normally used for initializing data fields or for initial settings of your class methods.
• Let's create a Constructor for our OLevel class:

• In above figure, you can see I have created a new method in our OLevel class and it has the same name OLevel.
• Constructors can also have parameters, so if we want to send some data from one class to another class, we can use these constructor parameters.
• So, now instead of hard coding the data in my new class, I am sending the data, when I am create new instance of class. i.e.

OLevel O1 = new OLevel ( " TEP " , " C# " );

• So, that way I can send multiple data just by creating new instance of class.
• You must have noticed that this C# Class Constructor doesn't have a static keyword in it so its an Instance Constructor.
• So, we can also add a static Constructor in C# class, which don't have any access modifier or return type and just have static keyword in its definition and is executed before instance Constructor.
• Moreover, Destructor in C# is used to clean up any resources used by the class and these destructors are called automatically by the garbage collector so we don't need to worry about them.
• Destructors can't take any parameters and they doesn't have access modifier or return type, they just have a tilled sign ( ~ ) in front of them.
• I have created static Constructor, Instance Constructor & Destructor in below code:

• You can see in above figure, that static Constructor is called first and then instance Constructor is called and finally we printed the Full Name.
• Here's the complete code used in this lecture:

using System; namespace TEPProject { class OLevel { string FirstName; string LastName; static OLevel() { // Static Constructor Console.WriteLine("\nStatic Constructor Called\n"); } public OLevel(string Name1, string Name2) { Console.WriteLine("Instance Constructor Called\n"); this.FirstName = Name1; this.LastName = Name2; } public void printStudentName() { Console.WriteLine("Full Name : {0} {1}\n\n", FirstName, LastName); } ~ OLevel() { // Destructor } } class Program { static void Main(string[] args) { Console.WriteLine("\n\nwww.TheEngineeringProjects.com"); OLevel O1 = new OLevel("TEP","C#"); O1.printStudentName(); } } }

So, that was all about Classes in C#, I hope you have understand their basic concept, we will gradually move towards complex codes. In the next session, we will have a look at Introduction to Namespaces in C#. Till then take care & have fun !!! :)

Introduction to Methods in C#

Hello friends, I hope you all are doing great. In today tutorial, I am going to give you a detailed Introduction to Methods in C#. It's our 12th tutorial in C# series. So far, we have covered all the basic concepts in C# and now it's time to move forward and have a look at some complex concepts. Methods have an important role in C# programming and if you want to be an efficient programmer then you must set your method controls correctly. Some methods have secret codes in them, which you don't want to give access to your developers, then you can set it private. We will cover such things in detail later, let's first have a look at Introduction to Methods in C#:

Introduction to Methods in C#

• Methods in C#, also called Functions, are extremely useful in optimizing the code, normally used to create a logic once and use it repeatedly.
• It happens in projects where you need to do a similar job at various places of your code.

• In such conditions, it's wise to create a small function of your repeated code and instead of adding those lines again and again, simply call the function.
• Here's the syntax of Methods in C#:

Access-Modifiers Return-Type Method-Name ( Parameters )  { // Method-Body } public void HelloWorld(){ Console.Write("Hello World !!!"); }

• Access-Modifiers: Access Modifiers are used to control access capability of any method / function. You can set them public, protected or private etc. We will discuss them later in detail.
• Return-Type: It decides what the method is gonna return, it could be void or any data type i.e. int, float, string etc.
• Method-Name: It's the unique name of the Method / Function, which can't be any reserved keywords in C#. It's should be meaningful so you can remember later.
• Parameters: Parameters are optional and are normally used to transfer data between methods.
• There are two types of methods available in C#, which are:
  • Instance Method.
  • Static Method.
• Let's discuss both of them separately, in detail:

Instance Method in C#

• Those methods, which doesn't have static keyword in their definition are called Instance Methods in C#.
• In order to call instance method in another method, we have to first create a new instance of that method and the invoke the method using dot operator.
• Let's have a look at how to create and call an instance method in C#:

• You must have realized by now that all the work we have been doing so far was in Main Method. That's the default method, the C# compiler first goes into and it's a static method as it has static keyword in it, which will discuss next.
• So, now in above figure, I have created a new method and I have used public (access-modifier) and void (return-type) and the Method-Name is PrintNames. I am using studentsNames array as a parameter.
• I have used the same code which we have designed in our previous lecture on For Loop in C#, so I have placed the foreach loop in my newly created instance method named PrintNames.
• Now in order to call this new method in Main method, I have to first create a new instance of this method's class and you must have noticed that the class name is Program at the top.
• Both of our Main & PrintNames Methods are placed inside Program class.
• So, in our Main function, I have first created a new instance of my class Program using new keyword:

Program P = new Program ( );

• After that, using this class instance P, I have invoked the PrintNames method using dot operator ( . ).

P.PrintNames ( studentsNames ) ;

• When you are calling your method, make sure you enter the parameters correctly as specified in its definition otherwise compiler will generate an error.
• You can specify multiple parameters separated by commas.
• So, that's how we can create and call an instance method, so now let's have a look at How to call static method in C#.

Static Method in C#

• Those methods, which have static keyword in its definition are called static methods in C#.
• In order to call a static method, we don't need to create a new instance of Program class.
• Instead, we can directly invoke a static method from Program class using dot operator ( . ), as shown in below figure:

• In above figure, I have created a new method called PrintNames2 and I have used static keyword in its definition, so its a static method in C#.
• So, now in order to call that method, I have used the name of class and then invoked the method using dot operator, using below code:

Program.PrintNames2 ( stringNames );

• We don't need to create a new instance of class for static method, that's the difference between static and instance methods in C#.

So, that was all about Methods in C# and I hope you have understood the difference between static and instance methods and how to invoke them. In the next lecture, we will have a look at Introduction to Namespace in C#, which is another important concept in C#. Till then take care & have fun !!! :)

How to use for Loop in C#

Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at How to use For Loop in C#. It's our 11th tutorial in C# series. Till now, we have seen two loops in C# which are IF Loop and while Loop and today we are gonna have a look at for Loop. For Loop is most commonly used loop in any programming language and if you have worked on any other language then you must be aware of its syntax. It is used to create repeated loop with specified number. Let's have a look at it in detail:

How to use for Loop in C#

• For loop in C# takes an integer variable as a Controlling agent, initialized at value V1 and ends at value V2, and the travel from value V1 to V2 depends on the Condition specified in () brackets.

• In both IF loop & while loop, the small brackets just have single argument, but in for loop, the small brackets have 3 arguments, separated by semicolon ; , which are:
  • First argument is initial value of variable V1.
  • Second argument is final value of variable V2.
  • Third argument is the condition applies on this variable i.e. increment, decrement etc.
• The loop will keep on repeating itself and we will also have the value of iteration in the form of variable value.
• Let's have a look at its syntax:

for (Initial Value V1; Final Value V2; Condition) { // body of for loop }

• Now let's have a look at a simple for loop in action

• Now you can see in above figure that I have initialized an integer variable x and in for loop, I have first assigned the initial value x=0 in first argument.
• In second argument, separated by ; , I have specified the final value x<10.
• Finally in third argument, I have incremented the variable x++.
• So, now when the compiler will first reach for loop, it will get x=0 and will run the code inside { } brackets that's why when I printed the value of x, it was 0 at first.
• After running all the lines in { } brackets, compiler will run the condition, which is to increment the variable, so in second iteration, the value of x=1, that's why in second line we have 1 on console.
• So, this loop will keep on running and the variable will keep on incrementing and when it will reach x=9, it will run the code lines in { } brackets and at the end it will increment the variable and will make it x = 10.
• So, now at x=10, the compiler knows in second argument of For loop, the variable's last value is 9 i.e. x <10. So when the value is not x<10, the compiler will leave for loop and go to next line below for loop.
• So, that's how For loop works, we can use it for running some lines of code repeatedly and the use of this variable inside for loop is quite helpful.
• Here's an example, where I have decremented the variable in third argument:

• From the console, its quite evident that now the variable's value is decreasing from 10 to 1, I have used x - - in condition part of For Loop.
• Now let's create an array of students' names and display all elements of that array using for Loop, we have discussed How to use Arrays in C# in our 6th lecture, you should recall that as well.
• Here's the code and it's output on console:

• As you can see in above figure that first I have initialized a new String Array of size 5.
• After that added some data i.e. students names, in each element of C# array.
• Next, I have used for Loop and initialized the variable and also assigned the first value 0 in first argument.
• In the second argument, I have used a Length property of array and our array's length is 5.
• So, this for loop will run from 0 to 4 and we can see at the console output that it has printed all the elements of array i.e. students names.
• That's how, we can use for Loop in C#, now let's have a look at how to use foreach loop in C#, which is kind of an extension of for loop.

How to use Foreach Loop in C#

• We have discussed Foreach Loop in our 6th tutorial on arrays and I have told you that we will discuss it in detail later, so now is the time to discuss it out.
• Foreach loop in C# is used to iterate through a collection or arrays from start till end. Collections could be ArrayList, HashTable etc. we will discuss them later.
• Let's first have a look at its syntax:

foreach (item in collections/arrays) { // body of foreach loop }

• This item variable will go through the whole array and will repeat the lines of code inside { } brackets.
• So, let's rewrite our previous example with foreach loop along with for loop and look at both results:

• Now you can see in above figure that we got similar results for both loops although foreach loop is quite simple and easy to look at thus reduces your code.
• In foreach loop, we are directly accessing the elements of array, while in for loop, we are getting elements using index of array.

So, that was all about for Loop in C# and we have also had a look at foreach loop. I'm just using simple examples rite now so that you got the clear idea of these loops. We have covered all the loops now so in next tutorial, we will have a look at Methods in C#. Till then take care !!! :)

Preparing for Engineering Certification Exams in the US

Hello friends, I hope you all are doing great. In today’s tutorial, we will have a look at Preparing for Engineering Certification Exams in the US.  Preparing to take an engineering exam can be an intimidating process because you know that it’s going to challenge your ability to recall and use what you’ve learned. Of course, with engineering being such a complex and broad field, involving plenty of math and science, it’s not surprising that high-level engineering exams can be some of the most difficult academic tests you’ll encounter during the course of your education. However, becoming a certified engineer is well worth the hassle when you consider the high salaries and prestigious job positions that come with it. To make sure you’re adequately prepared for your engineering certification exams, we will discuss some tips. So let's get started with Preparing for Engineering Certification Exams in the US.

Preparing for Engineering Certification Exams in the US

 Use Practice Exams

• If you’re looking for advice about how to prepare for an engineering exam, you’re probably still studying the Fundamentals of Engineering (FE). If that’s the case, you can take several practice exams to see what kind of questions and problems you’ll have to answer and solve on the real exam.

• That way, when the day of the exam comes, it’ll feel like another walk in the park. Using practice exams is a universally applicable strategy that can be applied to any subject, so be sure to work this into your overall study strategy.

Study the Fundamentals of Engineering

• As you may know, in order to become a licensed engineer, you must first complete a 4-year college degree program and pass the FE exam. After that, you’ll be working under the guidance of a Professional Engineer (PE) for another 4 years.
• From there, you’ll need to pass 2 intensive competency tests and apply for licensure with the state’s licensure board.
• It’s important to have a firm grasp on FE before you go into your first exam, as you’ll need to utilize what you’ve learned under the supervision of a PE.
• So, instead of just aiming to pass the exam and be done with it, you should go ahead and be prepared to assimilate and retain everything because you’re going to need it all eventually.

Study the Principles and Practices of Engineering

• The Principles and Practices of Engineering (PE) exam will be the second exam you’ll need to pass while you’re accumulating experience as a supervised apprentice. More than 25,000 interns take the PE exam every year.
• To give you an idea of how difficult this exam is, the annual pass rate for all students taking the test is below 65%. That means more than a third of engineer interns fail this exam and have to retake it.
• That’s a remarkably low pass rate when you consider the fact that those are students who have already done extensive studying in the field.
• The chances of passing such a test without a high level of sustained educational commitment are slim to none.

A Few Tips to Help You Pass the FE and PE Exams

• Now that you know what you’re up against, and you’ve learned the value of using practice exams during the preparation phase, here are a few tips you can use to maximize your chances of passing any major engineering exam:

Study every day for 3 months

• Experts recommend giving yourself at least 90 days of preparation at a minimum, with 6 months being an optimal time frame.

Create a study schedule

• Strictly adhering to a study schedule will ensure you’ll be done learning and ready to start re-capping weeks before the actual exam.

Read PE reference books

• You can find some incredible PE reference books online.
• Ultimately, if you heed the tips above and make sure you have a firm grasp of FE and PE, you should be able to pass your exam with flying colors.
