Personally, I would refactor this code slightly, even considering this
is a basic programming assignment. First, I would use "else" statements
so the user is not flooded with questions: the program would prompt one
at a time. Ideally I would refactor the decision logic into separate
classes and use polymorphism... but that is the sledgehammer approach
and probably not what the professor is looking for :-)
If you did want to prompt multiple things at a time, I would recommend
specifying how to separate the input: spaces? Commas? Three separate
lines? The program is ambiguous in this regard, currently, it accepts
any input for any variable, but only one input.
Also, thank you for being explicit about it being homework: you asked
the right questions in the right way, instead of saying "do my work
plzzzzzzz lol" like most people do.
