Turn to this book when you have questions. The authors are Harbison and Steele. If you become a C programmer, you will want and need this book. So you may as well get a copy now.
Another (more advanced) book is The C Puzzle Book.
It's older and I'm not sure it's totally up-to-date with the latest version of C. But it's still very valuable. If you finish this book, you will be a C ninja, and it isn't too hard.
K&R is outdated, in my opinion, because it is too skimpy.
But it is still a reference book not a get started with C guide.
