This is a code error:

Expand|Select|Wrap|Line Numbers
  1. #include <windows.h> // Sleep() 
  2. #include <mmsystem.h> // mciSendString()
There is no // Sleep() precompiler directive.

Lines beginning with # are precompiler only. You can't add stuff like comments. Everything on those # lines must be valid precompiler code.
