It is an eXtremely newbie question, but I don't know: What do a comment do? I didn't get anything about it.

As mentioned by others, comments are ignored by the compiler. They do not do anything in your program. They are there for you and others to better understand certain parts of your code. Perhaps you write some function that is fairly complex and hard to understand. You can leave some comments to remind yourself what it does and then leave some comments that give you a step by step breakdown. Comments are a standard practice in coding and can be especially useful for beginners. They are not a requirement, but strongly recommended.

A comment doesn't do anything... It's like a sticky note on a desktop! It's just used to remind yourself of something or to organize your code.
