Why there is 0 in output????????????😭😭😭😭😭😭

Question

#include <iostream>
using namespace std;

int main() {
int x;
int n;
cin >> x;
cin >> n;
double result;
double resultFinal=1;
if(n>0){
for(int i=0;i<=n;i++){
result = x/(n+i);
resultFinal = result*resultFinal;

}
}
cout<<resultFinal;
}

Answer 1

when n >0
at the end of the loop you will get a division where x < (n+i)
since it's an integer division it will return 0.
0 * resultFinal will always be 0
cast the division to return double instead.
