Description

Enhance the last assignment to include input validation. The enhanced assignment should check the values of day, month, and year entered by the user to ensure that they are OK. If they are not OK, the program should display an error message and return. The program should check the input values before computing the day number.

The program should validate the input values to ensure that:

Year value is from 2000 to 2099 inclusive.

Month value is from 1 to 12 inclusive.

Day value is valid for the given month and the year.

Testing

Input Test Run 1
