Finding The Power of a Number With Recursion in C.

#include <stdio.h>

long power (int num, int pow)

{

    if(pow)

    {

      return (num * power(num, pow - 1)); ///until pow=0; this function call it self

    }

    return 1;

}

int main()

{

    int pow, num;

    long result;

    printf("Enter a number: ");

    scanf("%d", &num);

    printf("Enter it's power: ");

    scanf("%d", &pow);

    result = power(num, pow); ///calling the function

    printf("
%d^%d is %ld", num, pow, result);

    printf("
");

    return 0;

}
