Calculating Factorials Recursively

Demo Code

#include <stdio.h>
long int factorial (int n);
int main (void)
{
    for (int j = 0; j < 11; ++j )
        printf( "%2u! = %lu\n", j, factorial  (j));

    return 0;/*from w w w  .j  a va 2 s .  c om*/
}

//Recursive function to calculate the factorial of a positive integer.

long int factorial (int n){
    long int result;

    if ( n == 0)
        result = 1;
    else
        result = n * factorial (n - 1);

    return result;
}
