Cross-posting is considered bad etiquette since it wastes people's time. You have someone answering a question that's already been answered on another forum because they didn't know about it.

You need to learn to use a compiler, period. You cannot program without experimentation. You cannot experiment without actually compiling and running programs. There are lots of good compilers and IDEs out there, including:

Code Blocks
Dev C++
Microsoft Visual Studio Express

The above are all free. Install one, type in your program, compile and run it.
