Using a while loop

Question

would anyone tell me why this code gives no output please ?

#include <iostream>
using namespace std;

int main() {
int num = 1;
int number;

while (num <= 5) {
cin >> number;
num++;
}
return 0;
}

Answer 1

All the while loop is doing is receiving a value for number. Nothing is being done with it. Tack on a cout inside the loop or at the end of the code.
Also, you're getting an input for number 5 times, and the newest one overwrites the last one. Only the last input will actually be stored.
