| Introduction
After writing the Game Programming Genesis series, I got a lot of E-mail from people asking me to clarify the bitwise operations I used in the sample programs. I use them all over the place in my code, enough that I don't really think about what I'm writing anymore, and so I neglected the fact that a lot of people don't see them used too often. This article is meant to be a complete introduction to bitwise manipulations using the C programming language. If you don't know C, no big deal. The ideas presented here are very general. The only things that will differ from one language to another are the characters used to represent the various operators.
I will go over the combinational operators AND, OR, and XOR, and show you some of the things they are commonly used for. I will also go over bitwise shifts, and their applications. But before that, in case you're very new to this, I'm going to run through a discussion of how numbers are represented in binary form, and some basic terminology. If you've gone that far already, which many of you probably have, feel free to skip over this first part.
