In c++ language, I already solved the problem and ran it fine. However, I am not sure if I can use hardcode. I know its unacceptable hardcode. Here’s the question from the exercise. (the Person, Student, Employee, Faculty, and Staff classes) Design a class name Person and its two derived classed named Student and Employee. Make Faculty and Staff derived classes of Employee. A person has a name, address, phone number, and e-mail address. A student has a class status (freshman, sophomore, junior, or senior). An employee has an office, salary, and date-hired. Define a class named MyDate that contains the fields year, month, and day. a faculty member has office hours and a rank. A staff member has a title. Define a constant virtual toString function in the Person class and override it in each class to display the class name and the person’s name. Write a test program that creates a Person, Student, Employee, Faculty, and Staff, and invokes their toString() functions.
