What's wrong with my Countdown Code in C++?

Question

#include <iostream>
using namespace std;

int main() {
int n;
cin >> n;
{
while (n >= 1) {
cout << n << endl;
n = n-1;
if (n % 5 == 0) {
cout << "Beep" << endl;
}}}

return 0;
}

it's currently 1 second off the requirement, for example it says "Beep" after 11 instead of 10

Answer 1

You can use n = n -1 or decrement(n--) outside if statement.
Also there is an extra "{}" before while loop

while (condition){
if (condition){
}
n = n-1;
}
