推荐答案

As already mentioned by Richard, the stdafx.h file is a Microsoft specific file used when enabling precompiled headers. If you don’t use Visual Studio or VS without precompiled headers it must not be included.



You should use a debugger to set breakpoints to find out why your program stops playing.



However, this line in IsGameOver looks suspicious:
