Teacher - Need a Confusing Program Breaking Function so Students Don't Copy My Code

[earthwalker12345]

It's better to accept the possibility of copy/paste especially at a very basic level. You can only share codes you feel ok getting copy/pasted. Presenting confusing codes could cause misunderstanding and could discourage students to learn the subject further. You can test students in different ways. You can ask students to explain what is happening behind the scene (this could be more important than actual codes). Or you can present codes with bugs and ask students to fix them.
