Question
In C++
Your role is to design a class called TrackProp. The class's purpose is to store a value that represents a property tracked hours and covert 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, street address and zip code, 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 trackProp objects are added together, the overloaded + operator should return the sum of the two objects' hour members
- Subtraction operator. When one trackProp 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.
Demonstrate each of your functions by creating multiple property class objects to show functionality. Thoughtfully consider how your output will show the details of your program
