Result is 120

#include <stdio.h>

int main()
{
int n;
while(scanf("%d", &n) == 1)
{
int r = 1;
while(n > 0)
r *= (n--);

printf("%d\n", r);
}
return 0;
}

Please don't double post. It is also appropriate to include your attempt at solving obvious homework problems. You won't learn by copying someone elses work. ;-)

I would just read in the input number, which it appears there should only be one, and then increment it.

Then I would create a while loop like:

while(num-- > 2){
        ..
        ..
}

Inside the loop, I would do the multiplication, and after the loop I would print the result.

@ ciphermagi: Too late, he's already been given the full solution in his duplicate thread.

#include <iostream>
int main()
{
using namespace std;
int a;
a = 5;
int b;
b = a;

while(a > 1){
b *=  (a-1);
a-=1;
}

cout << b << endl;
}

My output was 120. Hope this helps
