For and while loop count down

Question

Hi,

I have tired the count down app problem:
Given a number N as input, output numbers from N to 1 on separate lines.
Also, when the current countdown number is a multiple of 5, the app should output "Beep".

I tried the for loop but "for" some reason the counter doesn't count down. it goes through the loop once and that is all.
However when I used "while" loop it works fine, I am not sure why my "for" loop doesn't work as I expected it to work.

#include <iostream>
using namespace std;

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

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

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

return 0;
}

Answer 1

Enough is

for (int x = n; x >= 1; x-- )

Answer 2

Just miss out on the x
Thank you! JaScript

Answer 3

x =x-1 or x- -
