Haven't worked through the whole book yet, but I will say that I have other C or imperative-paradigm data structures book.
The topics are very meaningful: thorough emphasis on recursion (usually misunderstood by C programmers), backtracking (in games - yes, fun!), graphs, trees, that is, the standard gammut of topics, but all written amidst a very interesting text that makes a person who loves programming to never let the book down, because of all the /usefull/ stuff that's in it. For instance, he uses an editor as the common thread to discuss buffers, then implents it using arrays, stack, and linked lists. You end up having a /practical/ introduction to those issues and the implications therein. This is not "practical" in the sense that it's "dumb". This is "real" as in "real GOOD, USEFUL, WELL WRITTEN, WELL DESIGNED" code. C hacking as it should be done.
The code is written in crystal clear style (which is amazing for a C book), the author is keen on abstraction and library reuse. The excercises are great, and not dumb and mechanic.
There isn't any book like this one for C out of the several that I've seen.
If you want to learn C, after you learn the basics, this is THE book. I guess the other reviewer is right when he says that this must be the "SICP for C." And if you know anything about programming, you know that this is a big compliment.
The author is an Applied Mathematics graduate from Harvard and a professor at Stanford.
An excellent, excellent text! Addictive reading!
