there is a saying "whenever in doubt always follow K & R"...this book is a must have for every programmer
hehe I agree

The C Programming Language, 2nd Ed. Kernighan & Ritchie is a must have C book. They sell for bout $40 but you could probably get it off ebay for a cheaper price. The book is not one of them C bible. It's only 250 pages but it covers everything.
