THIS IS A C++ Program QUESTION!!! DO NOT ANSWER IN JAVA otherwise answer will be downvoted!!!

Thank you

Module 9

Question 2

(Payroll System Modification) Modify the payroll system discussed in the class. You are now required to include private instance variable birthDate in class Employee. Use class Date we have discussed in previous modules, Assume that payroll is processed once per month. Create an array of Employee variables to store references to the various employee objects. In a loop, calculate the payroll for each Employee (polymorphically), and add a $100.00 bonus to the persons payroll amount if the current month is the month in which the Employees birthday occurs.

QUESTION- Change the Hourly rate of the Hourly Employee and give 10% increase in hourly rate

PROG32.cpp: PLEASE EDIT THIS PROGRAM AS SAID IN THE QUESTION

#include "Employee.h"

#include "HourlyEmployee.h"

#include "SalariedEmployee.h"

#include "CommissionEmployee.h"

#include "BasePlusCommissionEmployee.h"

using namespace std;

int main()

{

vector < Employee * > employees( 4 );

// initialize vector with various kinds of Employees

employees[ 0 ] = new SalariedEmployee("John", "Smith", "111-11-1111", 800 );

employees[ 1 ] = new CommissionEmployee("Sue", "Jones","333-33-3333", 10000, .06 );

employees[ 2 ] = new HourlyEmployee("John", "Charles", "111-11-1111", 26, 80 );

employees[ 3 ] = new BasePlusCommissionEmployee("Bob", "Lewis", "444-44-4444", 5000, .04, 300 );

// polymorphically process each element in vector employees

for ( Employee *employeePtr : employees )

{

employeePtr->print(); // output employee information

cout << endl;

// get the basePlusCommission Employee to provide a raise

BasePlusCommissionEmployee *derivedPtr = dynamic_cast < BasePlusCommissionEmployee * >( employeePtr );

// determine whether element points to a BasePlusCommissionEmployee

if ( derivedPtr != nullptr ) // true for "is a" relationship

{

double oldBaseSalary = derivedPtr->getBaseSalary(); // get the old salary

cout << "old base salary: $" << oldBaseSalary << endl; //print old salary

derivedPtr->setBaseSalary( 1.10 * oldBaseSalary ); // provide a 10% raise

cout << "new base salary with 10% increase is: $" << derivedPtr->getBaseSalary() << endl; // get the new salary

} // end if

cout << "earned $" << employeePtr->earnings() << " ";

// downcast pointer

//@ STUDENT TO DO : Change the Hourly rate of the Hourly Employee and give 10% increase in hourly rate
