Query: BAD BAD BAD!

this is the worst computer book I have ever read. They don't teach you anything at all. All they do is tell you to type in code that they created, and don't tell you what to do. Then they say that they have additional code on their website. It's hard to find the code. And once you get the code, it doesn't work. This is the worst book ever. Please do not waste your money on it. Even the "For Dummies" books are better. It only has one chapter that teaches you how to program in C++ w/o using their code... and they don't teach you much at all. Don't waste your time or money.
