This was the first book that got me started off on C programming, and I would strongly recommend it, provided you dont mind overlooking the authors limited lingual skills and choice of words. (Thats the only reason I have rated this with 4 stars instead of a full five.) The exercises themselves are very interesting and challenging and let you test your mettle. All in all, a very good beginner level book to begin your career in C programming.
