Answer 1

It helps to tell people what to input with a multiline comment at the beginning of your code. To go even further, you can also write an example input in that same comment.

Answer 2

Leaving a short and easy instruction at the top is a good idea. To make sure, you could write it again as a comment or in your post (when it's an assignment).

Still many people will not read it and just hit RUN, so I think it is a good idea to set default values that are used in that case, so that your program doesn't fail no matter what the user does.

Answer 3

Add input-handlers, exception-handlers, Error handlers
