Can you help me understand this Computer Science question?

The assignment sheet and files needed are attached.

I would like to get an explanation of what we’re doing, because we’re demonstrating it in class.

it will be checked on Moss so please no plagiarism.

Nice written C++ code following the instructions and nothing more, we’re not professional,

so our code shouldn’t look like we are.

(student level coding to do everything that is asked in the .docx file, with comments + explanations to help us demonstrate the code in class)

take your time to make it look nice, student level C++ coding, follow every grading criteria.

(notes on what to say/do on our in class demo/presentation would be greatly appreciated)
