1.Functional Requirements: The owner of Duncan Miller Gallery does not like these EXIT_FAILURE crashes that the program causes. He thinks that it is a rather inelegant way to fix a problem. I totally agree.

Programming Requirements: Modify your code in main.cpp as follows:

When the program prompts the user for input, the code will check at that time for correct bounds. For example,

Prompt user for retail price

input retail price

while (retailPrice <0)

display error message

input retail price

end while

Programming Notes

Don't change anything in the member functions - we are just creating an higher-level form of validation. And yes, we are validating twice. But this stops the program from crashing with an EXIT_FAILURE and allows the users to fix their input mistakes.
