Well, what you want is asynchronous input. All of the methods provided by cin wait for enter. You will have to use system-specific functions for that, or use a library that will do it for you.

What you need to do is to not only process your logic in a while loop, but also listen from message pipe from your OS. If you want some more information about that one, please drop a comment.

#include

using namespace std;

int main()
{
   cout << "Enter a character";
   getch();
}
