Try reading online, it's cheaper:

ANY introductory book on C/C++ will have at least one full chapter dedicated to pointers and pointer arithmetic. The benefits of reading this stuff online are obvious:

1) It's free
2) You can try the examples on your own machine as you read the material... provided you have a text editor and a compiler.


Take care,
