Recursion

Recursion is very useful concept. Recursion, in very simple words, function calling itself. Sometimes, we need to repeat the function many...

Unlike the array, which stores the data in the variables of the same data type, Structures and Union are used for data storage in variables...

Pointers

So, now let's begin with the Advanced Part of C Programming. The first concept, we are going to learn about is pointers. So what are pointers?...

Functions

Functions are basically the block of codes which we have to use multiple times in the program like loops. Functions can reduce the number...
