Programming in C is probably the best introduction I've read to any programming language. It's the near-perfect example of how a computer book should be written, a pleasure to read, well-paced, challenging, addictive.
What's best with it, though, is that it has inspired great confidence in me. I *know* now that C is a language I can master.
So I've ordered K&R for a reality check. It should be arriving any day now.
