Chapter 11, Problem 4PC
Number of Days Worked
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.

- Cruise Recreational Activities Example Recreational activities include things like aerobics, shuffle board, and swimming. Each activity is identified by an activity code and includes other information such as description. Classes are offered for each activity. A class is uniquely identified by a combination of the activity code and the day/time at which it is held. It is assumed that a specific class will never be offered for the same activity at the same day and time, although it could be offered on a different day and/or time. Other information about a class includes the enrollment limit and the current enrollment count. A class will never include more than one activity. A passenger can sign up for a class as long as there is sufficient room in the class. Passengers are identified by a unique passenger number. Other information stored about passengers includes name, address, and age. Passengers have no limit on the number and type of classes they can sign up for.
