For anyone who has picked up a copy of K&R wanting to learn C and hit a wall I highly recommend C Programming: A Modern Approach, 2nd Edition by K N King.

Having read many books on C over the years I think King's book is without doubt the best intro book to C. K&R is great but it is a reference more than a tutorial in my opinion and is better to read once you have the basics of C (and programming) under your belt.
