Question

what will be the out for N=4

please explain the steps in details to how to get it., just the final answer is not enough.( I know the answer)

I need to understand the back and forth between two functions.

#include <stdio.h>

int factorial(int N)

{

    int result=0;

    printf("In factorial function: N=%d ", N);

    if (N==1)

        result=1;

    else

        result=N*factorial(N-1);

    printf("In factorial function: result=%d ", result);

    return result;

}

int main(void)

{

    int N;

    printf("Input N ");

    scanf("%d", &N);

    printf("The factorial of %d is %d ", N, factorial(N));

    return 0;

}

Explanation / Answer

1. printf("The factorial of %d is %d ", 4, factorial(4));
2. else part in factorial function
3. result = 4 * factorial (3)
4. else part in factorial function
5. result = 4 * 3 * factorial(2)
6. else part in factorial function
7. result = 4 * 3 * 2 *factorial(1)
8. if part in factorial function and return 1
9. result = 4 * 3 * 2 * 1
10. return result
