The Don Libes book, Obfuscated C and Other Mysteries [0], is a fantastic programming book, among my top ten. I think it's out of print, but Amazon has used copies.
If you like deconstructing obfuscated c, then you may also enjoy Obfuscated C And Other Mysteries by Don Libes. In addition to coding advice, it looks at some of the top entries from the Obfuscated C Contest, 1984-1991.
