Well, if nothing else all of my games include source. So if you don't find my code to be too obscure, maybe you can learn something from what my code says.
I have in mind to put more how to programming type topics in
my blog as I struggle with various features of the PSP. But I'm mostly productive because I work hard at what I do, and I've been doing it for a very long time (I started programming in 1980 when I was in grade 3).
I think that if you want to learn C++ or C you need to start with a book that teaches the basic programming concepts. Then you should spend time on wikipedia on how to do various algorithms. Then the rest should be possible to learn from looking at working code done by other people and trying out their ideas on your own.
