Void function doesn't print

Question

I am trying to write a code to print values using function and the program doesn't print anything and I don't know why. I know void function don't return any value so I put cout inside the function and I call is correctly

#include <iostream>
using namespace std;

void Print(int n){
    for (int i = 0; i <= n; i++){
        if (n%i == 0){
            cout << i << ' ';
        }
    }
    cout << endl;
}
    
int main(){
    int x;
    cin >> x;
    Print(x);
    return 0;
}

Answer 1

Start your loop from 1 in Print function. You can not mod a number with 0. Division by zero is not allowed.

Answer 2

When you run your program, it wont print anything. You have to enter a number first, then press Enter/Return, and then it should print something.

Assuming you do this and it still does not print, that will be because your Print has a loop that starts from i = 0 , and you then do n % i . Doing the modulo % operation with a right-hand-side operand of 0 is not going to work. Start the loop from i = 1 or something else >0 .

Lastly, your program will terminate in main at the return 0; right after the first Print . This means that most of your main won't actually be executed. This is probably intentional, but keep that in mind.

Fix these issues and make sure you enter a number into your program when it runs that is valid, like 12 , and it should print something.
