35 years ago, when I was told my 2nd freshman course in programming would be in Pascal, I bought the _Pascal User's Manual and Report_, read through it in one sitting, managed to remember most of it (Pascal is a small language) and was able to program in it - at a beginner level, of course. K&R is roughly the C equivalent. If you want the language and nothing but, then it should do you nicely.
My personal favorite, because it explains better (so I think) and dives into a little more depth where K&R leaves you to extrapolate on your own, is Peter van der Linden's "Expert C Programming" (Deep C Secrets): http://www.amazon.com/Expert-Programming-Peter-van-Linden/dp... . Also, I enjoy the author's entertaining style, and think it aids learning.
