Strange IPhone Request (Sleep/delay command)?

[MrLimble]

So I've got a somewhat unorthodox request for help. So I have an app to compiler c/C++ code. I've been trying to write a simple menu code. The problem is on iPhone, the cin>> command brings up a box GUI on screen blocking any text on screen so the user can not see what they are supposed to enter. Is there a way to make the code wait, or a just a delay command that will give the user enough time to read the code? The wait() command's header file will not work for whatever reason. Is there a specific iPhone library?
