What is recursion in C?

Question

Can anyone explain the recursion in C?

Answer 1

In programming, recursion is a function calling itself using the iterative approach to perform complex tasks. Here is an example to write recursive function in C:

void recursion() {

   recursion(); /* function calls itself */

}

int main() {

   recursion();

}

The C language supports recursion but you need to define an exit condition while defining recursion, otherwise it will go into an infinite loop.

Recursive functions are used for calculating the factorial of a number, generating the Fibonacci series, etc.
