NumDays, TimeOff, and Personnel Report

Complete #4, 5 & 6 . Please submit just one file for the classes and main to test the classes. Just create the classes before main and submit only one cpp file. Do not create separate header files. There is a sample NumDays class in a text file for you to use as a base.

oblem
4. NumDays Class
Design a class called NumDays. The class's purpose is to store a value that represents a
number of work hours and convert it to a number of days. For example, 8 hours would
be converted to 1 day, 12 hours would be converted to 1.5 days, and 18 hours would
be converted to 2.25 days. The class should have a constructor that accepts a number
of hours, as well as member functions for storing and retrieving the hours and days.
The class should also have the following overloaded operators:
Addition operator. When two NumDays objects are added together, the over-
loaded + operator should return the sum of the two objects' hours members.
Subtraction operator. When one NumDays object is subtracted from another,
the overloaded - operator should return the difference of the two objects' hours
members.
+
-
++
Prefix and postfix increment operators. These operators should increment the
number of hours stored in the object. When incremented, the number of days
should be automatically recalculated.
Prefix and postfix decrement operators. These operators should decrement the
number of hours stored in the object. When decremented, the number of days
should be automatically recalculated.
5. Time Off
NOTE: This assignment assumes you have already completed Programming Challenge 4.
Design a class named TimeOff. The purpose of the class is to track an employee's
sick leave, vacation, and unpaid time off. It should have, as members, the following
instances of the NumDays class described in Programming Challenge 4:
maxSickDays
sickTaken
maxVacation
vacTaken
A NumDays object that records the maximum number of days of
sick leave the employee may take.
A NumDays object that records the number of days of sick leave the
employee has already taken.
A NumDays object that records the maximum number of days of
paid vacation the employee may take.
A NumDays object that records the number of days of paid vacation
the employee has already taken.

maxUnpaid
A NumDays object that records the maximum number of days of
unpaid vacation the employee may take.
A NumDays object that records the number of days of unpaid leave
the employee has taken.
unpaidTaken
Additionally, the class should have members for holding the employee's name and iden-
tification number. It should have an appropriate constructor and member functions for
storing and retrieving data in any of the member objects.
Input Validation: Company policy states that an employee may not accumulate more
than 240 hours of paid vacation. The class should not allow the maxVacation object
to store a value greater than this amount.
6. Personnel Report
NOTE: This assignment assumes you have already completed Programming
Challenges 4 and 5.
Write a program that uses an instance of the TimeOff class you designed in
Programming Challenge 5. The program should ask the user to enter the number of
months an employee has worked for the company. It should then use the TimeOff
object to calculate and display the employee's maximum number of sick leave and
vacation days. Employees earn 12 hours of vacation leave and 8 hours of sick leave
per month.
