Try getting a book on C at your local library. I'm actually learning C right now, so I can't give you any programming tips, but I would like to suggest a couple books.
1. Programming C in 12 easy lessons by Greg Perry ISBN 0-672-30522-4
this book comes with turbo c++ (really 0ld version) on a disk. Its pretty old, so you can probably get it on amazon for under 5 bucks.
2. The C Programming Language
This book is a bit thin, but teaches complete ANSI/ISO C (ANSI = American National Standards Institute). Don't buy it at a bookstore (a screaming $42), but find this one on amazon too.
BWAHAHAHAHAHAHA
