Question

#include <iostream>
using namespace std;

int main() {
int n;
cin >> n;

//your code goes here
while (n>=1){
cout << n <<endl;
n--;
if ( n>= 1 && n% 5 == 0){
cout<<"beep"<<endl;
}
}
return 0;
}

Answer 1

while ( n > 0) {
cout << n << endl;
if (n % 5 == 0) {
cout << "Beep" << endl;
}
n--;
}
return 0;
}

Answer 2

Suppose we enter 15.

n is printed before it is evaluated. Then it is decreased by 1. So by the time your if-statement is reached, n is 14.
