Query: The best book on C

This book is meant for readers who already know some C programming. For those who are absolute beginners, just find some website that gives an introduction to the C language and then buy this book! That is all you need to start with.When I read through the first few chapters, I got to learn many things that I didn't know when I first learnt C. If you really want to 'understand' C and take your first steps to be a better C programmer, buy this book.
