C++
Lab 9B Inheritance

Class Production Worker

Create a project C2010Lab9b; add a source file Lab9b.cpp to the project. Copy and paste the code is listed below:

1. Next, write a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have member variables to hold the following information:

• Shift (an integer)
• Hourly pay rate (a double)

// Specification file for the ProductionWorker Class

#ifndef PRODUCTION_WORKER_H

#define PRODUCTION_WORKER_H

#include "Employee.h"

#include <string>

using namespace std;

class ProductionWorker // write clause here to derive from Employee base class.

{

private:

       // declare The worker's shift as int

       // declare The worker's hourly pay rate as a double

public:

       // Default constructor

       ProductionWorker() : Employee()

             { shift = 0; payRate = 0.0; }

       // Constructor

       ProductionWorker(string aName, string aNumber, string aDate,

             int aShift, double aPayRate) : Employee(aName, aNumber, aDate)

             { shift = aShift; payRate = aPayRate; }

       // Mutators

       void setShift(int s)

             { shift = s; }

       void setPayRate(double r)

             { payRate = r; }

       // Accessors

       int getShiftNumber() const

             { return shift; }

       string getShiftName() const

             {

       // write the logic for the getshiftName() accessor

             }

       double getPayRate() const

             { return payRate; }

};

#endif

2. The workday is divided into two shifts: day and night. The shift variable will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2.
3. Write one or more constructors and the appropriate accessor and mutator functions for the class.
4. Compile and run program. Copy and paste output into this word document.
