Recursions in C

Mechanism in which a function makes a call to itself is called as recursion.

Sample program to demonstrate recursion.

#include <stdio.h>

int getfactorial(int i)

{

   if(i == 1)

   {

      return 1;

   }

   return i * getfactorial(i - 1);

}

void  main()

{

    int i = 4;

    printf("Factorial of %d is %d\n", i, getfactorial(i));

}
