OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
#include <iostream>
using namespace std;
//creating an Abstract base class for the Employee
class Employee
{
public:
//declaring a pure virtual function
//which get overrided in the other derived classes
virtual float computeYIncome() = 0;
};
//create a class ExecOfficer derived from ExecOfficer
class ExecOfficer:public Employee
{
int salary;
public:
//constructor for the class
ExecOfficer(int s)
{
salary = s;
}
//overriding the base class function
float computeYIncome()
{
cout <<"The salary of Executive Officer is : "<<salary<<endl;;
}
};
class Worker:public Employee
{
int salary;
public:
//constructor for the class
Worker(int s)
{
salary = s;
}
//overriding the base class function
float computeYIncome()
{
cout << "The salary of Worker is : "<<salary<<endl;
}
};
int main()
{
//creating the objects of type worker and Executive Officer
Worker w(12000);
w.computeYIncome();
ExecOfficer E(60000);
E.computeYIncome();
}
main.cpp 27 19 ExecOfficer(int s) 20- { 21 salary = s; 22 } 23 //overriding the base class function 24 float computeYIncome) 25 { 26 cout <<"The salary of Executive Officer is : "<<salary<<endl;; } 28 }; 29 class Worker:public Employee 31 - { 32 int salary; 33 public: 34 //constructor for the class 35 Worker(int s) 36 { 37 salary = s; 38 } 39 //overriding the base class function 40 float computeYIncome () 41 - { 42 cout << "The salary of Worker is : "<<salary<<endl; 43 } 44 }; input The salary of Worker is : 12000 The salary of Executive Officer is : 60000 ...

Q3.
A. Encapsulation and Data Hiding is an important concept in OOP, illustrate how those concepts were implemented in the given employee program.
B. From the class ExecOfficer in the given employee program, derive a subclass called Manager which adds a monthly bonus attribute of type float to reflect the monthly compensation provided to executive officers with managerial position in addition to their base salary, and define the getData() and putData() functions for this new class.
