Comments are a very useful tool on programming, you can add stuff to your source code, this can be for you to understand better what you did in a certain spot of the code, maybe a remainder of something that needs to be done, or even for academic purposes by adding a comments for better teaching of the code.
The compiler ignores the comments, that means you can type in anything you like.
