For reverse engineering? You should use every single thing you can get your hands on that helps you learn. The K and R are the two people who wrote C. Of course you should read their if you want to learn C. Then read, and WRITE the code in, everything else you can get your hands on to learn a programming language. It may only take one book, it may take 10, but that's how you do it.
Then after that go learn Assembler, or even better, implement a compiler. You'd probably learn a ton of the things you need to know for reverse engineering code from just making one simple compiler.
