Assignment #9

Problem Statement

What to Do

1. Define a base class called Employee that contains a name (string), a social security number (string), and the respective accessor functions. It contains a function called print whose task is to output the name and social security number, and an overloaded operator< that orders employees by name. You should not use protected members. Include a two-parameter constructor, using initializer lists, and give all parameters defaults.
2. Next, derive a class called Hourly that adds a new data member to store an hourly wage (double). Its print function must print the name, social security number, and salary (with phrase "per hour"). It will certainly want to call the base class print. Provide an accessor and mutator for the salary, and make sure that its constructor initializes a salary.
3. Next, derive another class called Salaried that adds a new data member to store a yearly salary (double). Its print function must print the name, social security number, and salary (with phrase "annual"). Provide an accessor and mutator for the salary, and make sure that its constructor initializes a salary. Exercise the classes by declaring objects of type Salaried and Hourly via constructors and calling their print methods.
4. Provide a single operator<< that prints an Employee (by calling print). This method will automatically work for anything in the Employee hierarchy.
5. Make Employee abstract by providing an abstract salary accessor and mutator, and then decide which members should be virtual.
6. Continue by creating a class called PtrToEmployee that stores a pointer to an Employee. It should provide both print and operator< which applies the corresponding function to the employee that is being pointed at, as well as a constructor that can be called to have the pointer point somewhere (presumably the result of a new). The constructor's default parameter should be NULL. This class does not provide a destructor, since it does not actually create new Employees.
7. In order to hold all employees, create a class called Roster that is able to hold a variable number of PtrToEmployee objects. Roster should have a multiset of PtrToEmployee (ordered by name). Provide the capability to add an employee, and print the entire roster of employees. To add an employee, Roster::add creates a PtrToEmployee object and calls multiset::insert. Don't worry about error checks. To summarize, Roster has public methods named add and print.
8. Write a short test program, in which you create a Roster object, call new for both kinds of Employee, sending the result to Roster::add, and output the Roster via a call to print.
