Query: Dreadful

I was able (with considerable difficulty) to follow this book up to Hour 7.However, Hour 8. just lost me completely.Tried to follow the Listing examples 8.6 and 8.7 but didn't have a clue what "It's just an include file, so don't add it to the project". No explanation what a project, source file, header file or their relationship to each other. Informal remarks like this are downright misleading to anyone learning the language.It may be simple to you, Mickey Williams, but you don't explain the subject particularly well.Definitely NOT recommended.
