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:

The addition operator +. The number of hours in the sum of two objects is the

sum of the number of hours in the individual objects.

The subtraction operator - . The number of hours in the difference of two objects X

and Y is the number of hours in X minus the number of hours in Y.

Prefix and postfix increment operators ++. The number of hours in an object is

incremented by 1.

Prefix and postfix decrement operators --. The number of hours in an object is

decremented by 1.
