#C - Recursion

Recursion is a method of calling a function inside a function iteratively.

void recursion() {
   recursion(); /* function calls itself */
}

int main() {
   recursion();
}

In this case the function recursion calls a copy of itself to work on a smaller problem until some conditional is satisfied.

Any function which calls itself is called recursive function, and such function calls are called recursive calls.

Recursion is a method of solving problems based on the divide and conquer mentality and we break the problem into much smaller sub part's of itself, one of the subpart consists the a conditional to break the recursion.

Example

Creating a recursive function to find the factorial of a number
