Confused about Multi-File Programs

[RialnisMada]

Hey guys, I have been doing this tutorial for a little bit on this website, and it's been going great for a while. But the new section talking about how to create multi-file programs is really confusing me? This link:

http://www.learncpp.com/cpp-tutorial/18-programs-with-multiple-files/

How do I add two files to create one giant program using:

wxDev-C++?

Look for something along the lines of "add file to project" or "create new file + add to project".

Aha, found it. Didn't see at the top that there was a Project Tab.

Thanks!
