Information and technology, FahadTheITGuy, programming languages, web development, desktop development, C, C++, C#, visual basic, HTML, CSS, javascript, jQuery, MS SQL server, in this blog, we will learn different programming languages and implement them with examples, we are also going to learn web development in asp.net, asp.net core, asp.net MVC, asp.net core mvc, we also learn about databases in ms SQL server, we will also cover databases, data structures, data mining, and wisdom mining
What is Recursion in C++ programming language Today in this blog post we will cover the concept of Recursion in C++ programming language for beginners. So what is Recursion? And what is the use of Recursion in programming languages? We will cover the answer of these questions shortly. For now let us look at the basic introduction of Recursion. Recursion is a concept in which the function calls itself with in its own body, and breaks the complex problems into smaller and more manageable parts. So the first question was what is recursion? Basically Recursion is a method or technique which is used in programming languages and in this method the function calls itself. It means the function is called with in its own body. We will cover this concept with simple programming example which will make the concept of recursion crystal clear to the audience. The Second question was what is the use of Recursion in programming languages? Recursion simply breaks down complex problems or pro...

while loop in the C programming language
In computer programming languages there is a concept of control flow statements. In control flow statements we specify some conditions and based on those conditions whether they are true or false we run some iterative piece of code if the condition is true and terminate the control statement if the condition is false.
There are mainly three types of control flow statements that we use in our programs to get the desired result, these three types of control statements are
Three types of Control flow statements
1) do-while loop
2) while loop
3) for loop
In today's post, we will discuss the while loop control statement. while loop is also known as a pre-tested loop in which before running the piece of code the condition is examined first. If the condition is true only then the while loop will execute and if the condition is false then the while loop statement terminates.
In these control statements, the piece of code is iterated according to the given condition. Now let us look at the syntax of the while loop statement. Below is the syntax of the while loop in c programming.
Syntax of while loop in c program
while(condition)
{
// code to be executed
}
An expression is given in a while loop if the expression is true code repeats multiple times unless that condition becomes false. Now let us look at the simple example of the while loop. Below is the while loop example,
Explanation of the above coding example
In this while loop example program we simply declared an integer variable with constant value 1. After declaring and initializing this variable we are going to use this variable within the while expression and check for a condition that if the variable number has a value less or equal to 10 while(number<=10) than the given lines of code within curly brackets will repeat or iterate until number is less or equal to 10. At the end of this coding block, we are going to increment or add 1 in this number variable with each iteration until the number becomes equal to 10 and at that point, the while loop will terminate.
Congratulations as always, we did it again, we have successfully executed the while loop in C++ program.

Call by value and call by reference in C++ programming language Today we are going to talk about functions in C++ programming language. We will cover the concept of call by value and call by reference in C++ program. Before diving deep into this topic we will look at little introduction of functions in C++ program. By now we know that functions are one of the most important aspect of any programming language and the same is true with respect to C++ program. They are very important building block of C++ program. With the help of functions programmers and developers can divide a program into smaller and manageable parts. With in functions there is a concept of call by value and call by reference. Now we will understand and have a look on this important concept regarding functions. In functions we have studied about that how we can call a function in the main() method. In C++ we use arguments and parameters to send and receive data during function call respectively. We use arguments ...
Nested Loops In C++ Programming Language We have studied about loops in C++ programming language. There are three looping statements that we worked with so far i.e, while loop, do-while loop, and for loop. We know that we use loops when we want to repeat or iterate some piece of code according to our programming logic and requirement. Now the first question arises that what is a nested loop. At this point so far we already have knowledge about loops. Nested loops are nothing they are just a loop that is placed or resides completely inside another loop. In simple words it is a loop inside another loop. And remember one important point, the inner loop completes all of its iterations every single time the outer loop runs once. Basic Syntax Of Nested Loops In C++ Programming Language Now we will look at syntax of for loop , while loop , and do-while loop . Below is a syntax of for nested for loop in C++ programming language Below is a syntax for nested ...
