The C Programming Language (K&R) Book: Answers To Exercises (2002)

A complete collection of answers (and analysis) has also been available since at least 1988: <a href="http://amzn.com/0131096532" rel="nofollow">http://amzn.com/0131096532</a>

There's even space left, i.e. not all exercises have solutions published on that site. That's ... inspiring, heh.

Been working through this recently. Great link!
