 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...

What is Call by Value and Call by Reference in C Programming

What is Call by Value and Call by Reference in C Programming We use functions in programming languages like C, C++, C#, etc. Today we will cover some important concepts about functions that are implemented in C programming language. The topic we will cover today is the functions and the use of call by value and call by reference in C programming. This is a very important topic for functions. As we all know when we use functions we can pass values to functions from within the main program, the point where we call a function. There are two ways to pass data to functions in C language i.e.: Call by value and Call by reference . What is Call by value in C programming In Call by value, we pass the values of parameters or arguments that are used inside the main program. We only send variables' values to the function parameters. As shown in the above coding example, we cannot modify or change the values of parameters that are used inside the main program. In the...
