Copy paste source code undetectable

I have no knowledge on coding or programming, im currently watching a lynda guide on how to start, I have a source code cheat that im experimenting on as I learn by hands on. I don't understand what I am able to change without breaking it while still making it unique. Also what junk code can I add / where can I add it to?

Any explanation really helps a lot, and no I wont be selling the cheat and calling it mine I just want to learn.

If you feel you cant sum up what your trying to say in the post you can add me on skype if you want

trying to learn via a source code is kindove absurd....
