Exercise 2. Default, Default-Copy, and Argument Constructor

Employee Class (from Ch 13 Program Challenge 2)

Write a class named Employee that has the following member variables:
name. A string that holds the employee s name.
idNumber. An int variable that holds the employee s ID number.
department. A string that holds the name of the department where the employee works.
position. A string that holds the employee s job title.

Write appropriate mutator functions that store values in these member variables and accessor functions that return the values in these member variables. Once you have written the class, write a separate program that creates three Employee objects to hold the following data.

A 4-argument constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee s name, employee s ID number, department, and position.
A 2-argument constructor that accepts the following values as arguments and assigns them to the appropriate member variables: employee s name and ID number. The department and position fields should be assigned an empty string (“”).
A default constructor that assigns empty strings (“”) to the name, department, and position member variables, and 0 to the idNumber member variable.
A default Copy constructor that assigns previously created object instance to a new instance.

// Define the Employee Class below:

// Function prototype
void displayEmployee(Employee);

// Driver program to demonstrate the class
int main()
{
// Create an Employee object to test constructor #1.
Employee susan(“Susan Meyers”, 47899, “Accounting”, “Vice President”);

// Create an Employee object to test constructor #2.
Employee mark(“Mark Jones”, 39119);
mark.setDepartment(“IT”);
mark.setPosition(“Programmer”);

// Create an Employee object to test constructor #3.
Employee joy;
joy.setName(“Joy Rogers”);
joy.setIdNumber(81774);
joy.setDepartment(“Manufacturing”);
joy.setPosition(“Engineer”);

// Display each employee’s data.
