Question

Write a C++ program

Write a class named Employee that has the following member variables:

• name A string that holds the employee name
• idNumber An int to hold employee id number
• department A string to hold the name of the department
• position A string to hold the job position

The class will have three constructors:

1. A constructor that accepts all the internal data such as:

Employee susan("Susan Meyers", 47899, "Accounting", "Vice President");

2. A constructor that accepts some of the information and assigns an empty string to the missing data such as:

Employee mark("Mark Jones", 39119);

Then the missing data will be filled in by mutator member functions.

3. A constructor that accepts no information ( the default constructor ) such as:

      Employee joy;

Then the missing data will be filled in by mutator member functions.

Write the appropriate mutator and accessor functions for all the data of the Employee class. See below for the names to use for these functions. Examples would be setPosition and getPosition etc…

Write a member function of the Employee class to display all the information in the class called displayEmployee

Then use the following driver program to test your class:

// 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.

   displayEmployee(susan);

   displayEmployee(mark);

   displayEmployee(joy);

   system(“pause”);

   return 0;

}//end main

Sample output:

Name: Susan Meyers

ID Number: 47899

Department: Accounting

Position: Vice President

Name: Mark Jones

ID Number: 39119

Department: IT

Position: Programmer

Name: Joy Rogers

ID Number: 81774

Department: Manufacturing

Position: Engineer

C++ Program:

#include <iostream>
#include <string>

using namespace std;

//Class definition
class Employee
{
private:
//Data members
string name;
int idNumber;
string department;
string position;
public:

//Constructors
Employee(string n, int id, string dept, string pos);
Employee(string n, int id);
Employee();

//Getter methods
string getName();
int getIdNumber();
string getDepartment();
string getPosition();

//Setter methods
void setName(string);
void setIdNumber(int);
void setDepartment(string);
void setPosition(string);
};

//Setter Methods
void Employee::setPosition(string p)
{
position = p;
}

void Employee::setDepartment(string d)
{

}

void Employee::setIdNumber(int id)
{

}

string Employee::getPosition()
{
return position;
}

string Employee::getDepartment()
{
return department;
}

int Employee::getIdNumber()
{
return idNumber;
}

string Employee::getName()
{

}

//Default Constructor

//Arg-Constructor

//Arg-Constructor
Employee::Employee(string n, int id, string dept, string pos)

//Display function

}

// Driver program to demonstrate the class
