Answer 1

You shouldn't output a, but f.

Answer 2

Сергій Гавриленко I don't think he wanted to make a perfect factorial calculator, and you can calculate the factorial of the number with loops too

Answer 3

This is not a factorial calculation. Factorial is calculated using recursion. In addition, the program does not cut negative numbers and zero.

Answer 4

#include <iostream>
using namespace std;

int main() {
int a,f,n;
f=1;
cin>>n;
if (n==0)
cout<<'1';
else if (n<0)
cout<<"No factorial for negative numbers.";
else {
for(a=1;a<=n;a++){
f*=a;}
cout <<f;}

return 0;
}
