(Sorry for this really stupid question, I just started learning C++ yesterday at school.) How do you run a C++ program? (We only learned how to write one yesterday)
Well, you need a compiler, such as Visual C++ Express or the Bloodshed Group (both free).
For VC++:
You need to open a 'new project' then insert all of your source code into there. After that, you need to go to build -> build project and the .exe should appear. It's somewhere in My docs/Vis C++/projects/<project name>/
For Bloodshed:
I don't use it, so someone else will have to help you here.
