CS 1410 Programming Lab #10
Templates and Polymorphism with Virtual Functions
Assignment
Modify the code from Lab #9, making Employee into an abstract class and adding a virtual
function to SalesEmployee, SalariedEmployee, and WagedEmployee. Modify the Lab #9 driver
program to place employee objects into a circularly linked list as demonstrated in class.
1. Modify the CList class to make it a “templatized” class
a.
Copy the code from CList.cpp into Clist.h (between the class declaration and the
closing #endif)
b.
Add “template <class T>” before the class and before each member function
c.
Modify all function signatures to reflect the templatized class scope: CList<T>::
d.
Replace Employee with T 2. Modify the Lab #9 driver to place the instantiated employee objects into an instance of
CList
a.
Include the CList header file
b.
Instantiate a circularly linked list
c.
Insert each new employee object (e.g., we and se) in the list
d.
Discard the cout statements at the end of cases 1, 2, and 3
e.
Implement case 4, which calls the CList list function 3. Employee class
a.
Make the Employee class abstract by adding a pure virtual function named
calcPay:
virtual double calcPay() = 0;
b.
Add a “getName” function to return the employee’s name (this is an accessor or
getter function)
c.
Add a virtual display function to display (to cout) the employee’s name,
address, and birth date 4. WagedEmployee class
a.
Add a virtual function named calcPay: double calcPay() to calculate and
return a waged employee’s pay
i.
A waged employee’s pay is his/her wage times the hours worked
b.
Add a virtual display function that
i.
Calls the Employee display function
ii.
Displays the employee’s wage, hours, and pay (i.e., calls calcPay) Page 1 of 2 5. SalariedEmployee class
a.
Add a virtual function named calcPay: double calcPay()
i.
A salaried employee’s pay is his/her salary divided by 24
b.
Add a virtual display function that
i.
Calls the Employee display function
ii.
Displays the employee’s salary and pay (i.e., calls calcPay) 6. SalesEmployee class
a.
Add a virtual function named calcPay: double calcPay()
i.
A sales employee’s pay is his/her salary (call the salaried employee’s
calcPay function) plus commission times sales
b.
Add a virtual display function that
i.
Calls the salaried employee’s display function
ii.
Displays the employees commission, total sales, and pay (i.e., calls
calcPay) Grading
