Why do this code output “Beep” in the bottom? It has to stop after number “5”, no?

Answer 1

Zero % any number yields zero.
The `if` conditional verifies that <n> % 5 == 0 and prints "Beep"
Notice you subtract <n> before the `if` conditional block. When <n> was 1, code prints <n>, subtract it by one, and then <n> (being zero) gets passed to `if` conditional for verification.

Answer 2

Move the line `n = n - 1` under the `if` conditional block. As it is now, value of <n> is subtracted before the `if` conditional evaluates whether <n> was fully divisible by 5.

Answer 3

thank you for explaining!<3

Answer 4

#include <iostream>
using namespace std;
int main() {
int n;
cin >> n;
while (n > 0) {
cout << n << endl;
n = n - 1;
if (n % 5 == 0) {
cout << "" << endl;
}
}
return 0;
}

Answer 5

I know that, the question is why its produces "boop" after 1 even though 1 is not divisible by 5?

Answer 6

No, the "Beep" came from zero, when <n> gets to one, it then decremented to zero, then `if` conditional gets <n> value as zero, not one.

Answer 7

Assuming that you want the program to output "boop" if the no. Is divisible by 5 and output the no if it's not divisible by 5
Try this
#include <iostream>
using namespace std;
int main() {
int n;
cin >> n;
for(int i = n; i > 0; i--){
if(i % 5 != 0){
cout << i << endl;
} else {
cout << "boop" << endl;
}
}
return 0;
}

Answer 8

so 0%5 is completing the conditional? why so?
