Chapter 7, Problem 4PC
Car Class
Write a class named Car that has the following member variables:
• year. An int that holds the car’s model year.
• make. A string object that holds the make of the car.
• speed. An int that holds the car’s current speed.
In addition, the class should have the following member functions.
• Constructor. The constructor should accept the car’s year and make as arguments and assign these values to the object’s year and make member variables. The constructor should initialize the speed member variable to 0.
• Accessors. Appropriate accessor functions should be created to allow values to be retrieved from an object’s year, make, and speed member variables.
• accelerate. The accelerate function should add 5 to the speed member variable each time it is called.
• brake. The brake function should subtract 5 from the speed member variable each time it is called.

Design a Ship class that has the following members:
A member variable for the name of the ship (a string)
A member variable for the year that the ship was built (a string)
A default and parameterized constructor and appropriate getters and setters.
A toString method that displays the ship’s name and the year it was built.
Design a CruiseShip class that is derived from the Ship class. The CruiseShip class should have the following members:
A member variable for the maximum number of passengers (an int)
A default and parameterized constructor and appropriate getters and setters.
A toString method that overrides the toString function in the base class. The CruiseShip class’s toString function should display only the ship’s name and the maximum number of passengers.

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. When they…arrow_forward
