You are using a Microsoft compiler, and it creates projects that, by default, use precompiled headers. If you want to use precompiled headers then the very first include file must be stdafx.h

#include "stdafx.h"
// other stuff here

If you don't want to use precompiled headers then go to Project --> Project --> C++ tab --> Precompiled Headers and turn them off. (Assuming VC++ 2005/2008 compiler)

If you don't want to use precompiled headers then go to Project --> Project --> C++ tab --> Precompiled Headers and turn them off. (Assuming VC++ 2005/2008 compiler)

And when creating a new project, be sure you're selecting a Win32 Console application, and on the Application Wizard you go to the second tab (Application Settings) where you check Empty Project.
