An excellent book, and one which stands right next to K&R in my opinion, as a standard reference book on the subject of the C language. It still has much relevance today - many C projects I've seen being written by the new generation of developers could benefit from having this book become standard reference material everywhere. I can't recommend it enough.

This is an excellent book...but I would not recommend it to beginners. Read "Head First C" first, then maybe this book. Would also recommend "21st Century C."
