Question

For Practice It, do we need to include comments in our codes?

Answer 1

It is not necessary to include comments when coding in Practice It.

You should follow other conventions (good indenting, naming conventions for methods and variables, using descriptive names for methods and variables, etc.) even though Practice It doesn't check for that either when testing that your code produces the correct results.

Answer 2

I don't think we have to use comments on practice it!

Answer 3

Unless the question you are answering asks for it, you do not have to include comments in your code. Likely, for homework and such, the professor would appreciate a explanation as to what your code is trying to do though.
