In the previous topic, we have discussed data types in C++ in detail. Today we will discuss variables and constants in C++.
A named memory location or memory cell is called a variable. The program's input data and its results are stored in variables during execution. During the execution of the program, the value of a variable can be changed but its name can not be changed.
Variables are created in random access memory. As we know that RAM is a temporary memory so data stored in it is also temporary. It can only be used during execution. When the program ends, the data stored in the variable is automatically removed.
In C++, all the variables are declared first:
Name of variable: an identifier that represents a memory location.
Address of v ...
Hello friends, I hope you all are fine and having fun with your lives. In today's tutorial, we are gonna have a look at How to use C# String Variables in your C# Projects. In the previous tutorials, we have a look at How to use C# Int Variables and also have seen How to use C# Double Variable. So, now today we are gonna see how to use C# String Variable.
We have already discussed the variables in detail so I hope that you must have the idea of what variables are and if you don't then you must read the previous tutorials first. The code is also given below in the tutorial. So, let's get started with How to use C# String Variables:
How to use C# String Variables ???
C# also supports string variable, a string variable can save anything in it in t ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to elaborate you, how to make Arduino Projects for beginners. Before gong into the detail of this tutorial first of all I would like to explain you a bit about Arduino. Arduino is an open source micro controller. A lot of help is available online so its user friendly hardware. Most of the students prefer to do work on this device.
Arduino is a low cost high performance device. Due to its cost effectiveness and open source feature it is commonly available in the market these days. An amazing thing about Arduino is that students can take help online with a lot of examples regarding any of the task. There are thousands of Arduino projects are available online f ...
Hello everyone, I hope you all are doing great. Today, I am going to start this new series on ASP.NET Core and it's our first tutorial in this series. I will start from basics and will slowly move towards complex concepts. So, if you haven't worked on ASP.NET then you don't need to worry about that but you must have some basic knowledge of C# and object oriented programming.
I will use Visual Studio 2019 for these tutorials, it's community version is free to use and I will use C# language for developing ASP.NET Core web applications. So, let's first have a look at what is ASP.NET Core:
Introduction to ASP.NET Core
ASP.NET Core (originally deemed as ASP.NET xNext & was going to named as ASP.NET 5) is ...
Hi everyone! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to P6KE220A.The P6KE200A is a transient voltage suppressor (TVS) diode that uses clamping action to provide circuit protection against overvoltage. It is widely used in low-voltage supplied ICs and MOS technology due to its quick response to transient overvoltages. For P6KE200A the clamping voltage is 246V and the breakdown voltage is ranged from 190V to 210V.
I suggest you read this entire post till the end as I’ll detail the complete introduction to P6KE200A covering datasheet, pinout, features equivalents, and applications of this component P6KE200A.

The P6KE200A is a transient voltage suppre ...
Moving complex machinery across the country is no small feat. It demands meticulous planning, organization, and utmost caution throughout each step of the process. To that end, let’s discuss eight best practices that can streamline your move and ensure your equipment arrives at its new home intact and functional.Understanding Your Equipment
When gearing up for a cross-country move of complex machinery, the importance of gaining deep insights about your equipment cannot be overlooked. Here are several points you need to consider:Identify sensitive components: Knowing which parts of your machinery are delicate or more vulnerable can help avoid potential damage during transit.Analyze dismantling options: In some instances, disassembly may simplify transportation and reduce risks.Evaluate wei ...
Hi Friends! We are here to help you with valuable information keeping in view of your needs and requirements. This is a platform where you get knowledge related to engineering & technology and anything exhibits technical aspect. Today, I am going to give a quick review of one of the best PCB fabrication houses called JLCPCB.
PCB plays an important role in the execution of many projects. A recent surge in an innovative technology has removed the need of joining various electronic components using old methods where you required an end to end wiring to place components together. This is where PCB comes into play.
JLCPCB Fabrication House
If you take a deep interest in the embedded system, more often than not, you need to fabricate the PCB. It ...
Hello readers, I hope you all are having fun in your lives. Welcome to the 2nd Chapter of Section-2 in the ESP32 Programming Series. In today's lesson, we'll go over another built-in feature of the esp32 module that helps it stand out from the competition: BLE or Bluetooth Low Energy. In the previous tutorial, we discussed the Classic Bluetooth in ESP32, which is considered the predecessor of Bluetooth Low Energy(which we are going to discuss today). We will first look at, what is BLE? and why is it used?, and then will design some examples to utilize the ESP32 BLE in Arduino IDE.
What is BLE?
There have been numerous adjustments and upgrades to Bluetooth's characteristics since its inception, where Bluetooth 4.0(also called BLE or Bluetooth Smart) is the most influential.
B ...
Fluid mechanics is considered to be one of the essential branches of Mechanical Engineering. Fluid Mechanics comprises two words, fluid, and mechanics, with different meanings and research criteria. In this article, I will extensively introduce fluid mechanics and its importance in daily life. So without wasting any time, let us start:
Introduction to Fluid Mechanics
What is Fluid?
We remember in the early classes, we used to study three states of matter, and afterward, they became four named: Solid.Liquid.Gas. Plasma.
The definition of fluid is the state of matter that can be liquid or solid. We might have noticed that whenever the matter is in any stage, the criteria to know its state is to understand how much stress it can bear, and we name th ...
Hello friends, I hope you all are doing well. In today's tutorial, we will have a look at Key points to increase productivity in Construction Companies. The McKinsey Global Institute (MGI’s) Reinventing Construction: A route to higher productivity report showed many interesting results. For example, did you know that the lagging construction productivity costs the global economy 1.6 trillion dollars a year? The construction industry has a productivity problem, and the Coronavirus crisis - shutting down sites and limiting the number of people working on essential sites - will inadvertently raise it even higher. The report also shows the reasons behind it:
Stringent regulations and dependence on public sector demand
Informality (and sometimes ev ...
