I have this book at home, have read it and although it covers a lot in a short volume, I didn't get out of it as much as I did out of C Programming: A Modern Approach by KN King. Once I bought King's book, C made a lot more sense, the book was fun to read and follow. K&R's book was, to me, less "how & why" but more "how". Pointers, in particular, is what I enjoyed more in King's book. That chapter alone made buying the book worth its money.
