title: Resources to learn bitwise programming?
body: <p>I am a c++ programmer and occasionally I'll come across some code that is using bitwise operators to manipulate things at the bit level, but I have no real understanding of those concepts. So I would like a resource to help me learn it so well that it becomes second nature. Does anyone know of good resources for this? A google search did not provide me much useful information. Maybe I'm not sure what to look for. Thanks!</p>
