    So basically, non-pointer variables are limited by memory, and pointers are free to use as much memory? so to speak?
    Any variable, including a pointer, has a given size. A pointer may point to a region of memory only limited by what is available to the program.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.

    You guys should definitely consider a thanks button. I'm having the urge to do it.

    Yeah, and I could give others who are trying to learn C/C++ programming aswell, a recommendation to go to cprogramming.com, and the forums for help.
