The C cookbook
by Dhaivat Pandya
C is a pretty awesome language.
Its minimalistic and powerful. You can write C on everything. Blazing fast.
But, its not a language for the faint of heart. Writing good C code requires experience with the language, or maintaining and debugging applications becomes a nightmare.
This book will help you attain that level of familiarity fairly quickly; and, you can use it as a reference when you get stuck.
So, what are you waiting for?
