I need to get a list of numbers from the user, two by two, terminated by ctrl+d. I tried something like what was asked here: the question on while (cin >> )

but it only seems to work with strings, I tried a whole bunch of things, but cant get it to work.

For example, the following code accepts one pair of ints, and then ends:

#include <iostream>
using namespace std;
int main(){
    int x,y;
    while (cin >> x >> y) 
    {
    cout << "x: " << x << endl;
    cout << "y: " << y << endl;
    }
}

When testing it locally, there is no error. – Benson Lin Sep 08 '16 at 09:39
@BensonLin same here, no error. – YetAnother Sep 08 '16 at 09:41
I edited the question. There is no error, but it only takes one pair of numbers. – Kessem Clein Sep 08 '16 at 09:41
do you know what `cin >> x >>y` returns? – Hayt Sep 08 '16 at 09:45
I think it's correct program. what is your problem? what compiler are you using? – Raindrop7 Sep 08 '16 at 12:38
