I am trying to make a short text game with c++ to help me learn the language. I have made a version that basically displays texts, waits for an input, once the input is received it displays text, and so on. What I want to do now is make it so that it doesn't wait for the input. Real-time if you will. So certain values keep changing while the player is sitting, and if he sits for too long that game changes in a major way.

My problem is that I can't figure out how to incorporate this in a my game loop. I have a while loop that has a input function, an update function, and a display function. Is this just something I have to do with a wait function?

(I am just using Visual C++ and nothing else).

Thank you.
