}

This my code and the problem is with the if statement. That's when the error message appears :(

Don't worry, i worked it out myself but just incase anyone else has a similar problem you need two equals signs like this == in the if statement. Also if you use windows visual c++ you need this header file. #include <StdAfx.h>

You only need <stdafx.h> is you have a Win32 application as opposed to a Win32 Console Application project where you have created as empty and not using precompiled headers.
