Entering 2 values until a specific character key is pressed in C++?

Question

I have a C++ program, where I want to read 2 values until a specific character key is pressed - in this case '0'. I would like to ask how can I accomplish that in C++ without complicating the program too much? Thanks in advance.

Pseudocode:

    #include <iostream>

    using namespace std;

    int a,b;
    int main(){
        while ('0' is not pressed) {
            cin>>a>>b;
        }
    }

Answer 1

如果您在 Windows 上，您可以执行if (GetAsyncKeyState(VK_A) && GetAsyncKeyState(VK_B)) { //run subroutine }作为捕获键盘输入的一种快速简便的方法。

Answer 2

You may try something like this:

while(1)
{
  cin>>a;
  if(a != 0)  cin>>b;
  else break;
  if(b == 0)  break;
}
