lol, you don't need college to learn C silly :P
there's like a gajillion tutorials online about it XD
or you could do what i did:
read like there's no tomorrow.
I picked up a C++ for dummies.
Then somebody helped me out with a more C style, and understanding more of what is actually going on behind the scenes in C++ (wow, i was amazed at the abuse I applied to std::string type). Next the same guy taught me the basic in's and out's of win32 API. But, then i decided to myself 'hm...linux is a wonderful thing, i mean think about how much it shares' and i also saw that thread 'how to hack on linux' and 'how to hack on mac' so...i decided i would learn the GTK+ api. I found everything i needed online, and in a few books, just now going to high school. don't let the world set your limits, make your own. in that case, you'll be much happier ^_^
