How to control using the keyboard?

Question

Programming

There was a need to make control in the application via the keyboard, but I did not find anything sensible anywhere, only scraps or not quite what I need. For example, I want to control a cube through arrows. Throw some material, I will be glad :) Also, if anyone knows how to ATTEMPT to read for a certain time, well, for example, while the cube is standing, try to count the symbol / number for a second, if it is not there, then at the end of the time stop trying. Thanks in advance

snake C++ -> https://code-live.ru/post/cpp-oldschool-snake/
------------
well, you can track keystrokes in a separate thread (google: threads C++)

while(1)
    {
        ch = getch();
        code = static_cast<int>(ch);
            if(ch == 27) // если клавиша esc
                exit(0);
    }

and set some flag, they say the key was pressed
Next, in the drawing function, check this flag and do something
-------- Is there a GetAsyncKeyState
function, does it asynchronously check whether the key is pressed? https://msdn.microsoft.com/en-us/library/windows/d... key constants here https://msdn.microsoft.com/en-us/library/windows/d...

#include <iostream>
#include <Windows.h>

using namespace std;

int main()
{

  while (1)
  {
    cout << "DRAW!!" << endl;

    if (GetAsyncKeyState(VK_SPACE) != 0)
    {
      cout << "jump!" << endl;
    }

    _sleep(100);
  }

  return 0;
}

* the function receives the state of the key even when the window is not in focus, it is minimized somewhere
