i L A B O V E R V I E W
Scenario and Summary
We have two separate goals this week:
We are going to create an abstract Employee class and an abstract CalculatePay() method. The abstract Employee class will prevent a programmer from creating an object based on Employee. Only objects based on Salaried and Hourly will be allowed. The abstract CalculatePay() method in Employee will force the child classes to implement CalculatePay().
We are going to implement Polymorphism and dynamic binding by creating generalized methods that accept generalized Employee objects to collect input, and display information. In the Main method we will pass derived objects of the Employee class into these generalized methods.
Deliverables
Due this week:
Capture the console output window and paste it into a Word Document.
Zip the project folder.
Put the zip file and screenshots (Word document) in the drop box.

STEP 1: Understand the UML Diagram
Notice in the updated UML diagram, that the Employee class is designated as abstract by having the class name Employee italicized. Also, the CalculatePay method is also italicized, which means that it is a pure virtual function and needs to be implemented in the derived classes.
Explanation / Answer
//Run the prgram using visual studio 2010 csharp
public abstract class Employee
{
//abstract methods
public abstract void calculatePay();
public abstract void CollectEmployeeInformation();
public abstract void DisplayEmployeeInformation();
}
//HourlyEmployee class emplementing abstract Employee class
class HourlyEmployee:Employee
{
string firstName;
string lastName;
char gender;
int noOfdependents;
string healthInsure;

int wage;
int hours;

}

//@override abstract method dispaly employee information
