Here's a good tut for getting started out:

I'd say C++ is pretty dry for a beginner to read. Keep the wikipedia up to learn what words like "Preprocessor" means. Even if you do use the wiki it still gets confusing. For instance:
"A preprocessor is a program that processes its input data to produce output that is used as input to another program"
This will be quite fun. Ecspecially when I whip out my dusty Physics book.
