How to pause for certain amount of time

[Ch1156]

I remember it was something like

whatever(200);

I dont know what the keyword that goes where whatever is called. Its not system(pause); what makes the system stop for the amount of time i specify in the parenthesis? i forget?

It's Sleep. And it's not a keyword, it's a function part of the WinAPI:
