Answer to Question #194018 in C++ for Aduu

Question

Create an abstract base class called Employee. Use this class to store employee details such as name,designation, basic_pay, DA, HRA, salary. Include a virtual method to compute salary. Derive two classes called Manager and Workers to include pay and allowances of employees to calculate total salary.

Answer 1

#include <iostream>
#include <string>


using namespace std;


class Employee{
private:
	//name,designation, basic_pay, DA, HRA, salary
	string name;
	string designation;
	double basic_pay;
	double DA;
	double HRA;
public:
	//Constructor
	Employee(){}
	Employee(string name,string designation,double basic_pay,double DA,double HRA){
		this->name=name;
		this->designation=designation;
		this->basic_pay=basic_pay;
		this->DA=DA;
		this->HRA=HRA;
	}
	~Employee(){}
	//virtual method to compute salary.
	virtual double calculateSalary(){
		return basic_pay+DA+HRA;
	}
	virtual void display(){
		cout<<"Employee name: "<<name<<"\n";
		cout<<"Employee designation: "<<designation<<"\n";
		cout<<"Employee basic pay: "<<basic_pay<<"\n";
		cout<<"Employee DA: "<<designation<<"\n";
		cout<<"Employee HRA: "<<HRA<<"\n";
	}
};
//Derive two classes called Manager and Workers to include pay and allowances of employees to calculate total salary.


class Manager:public Employee{
private:
	double pay;
public:
	//Constructor
	Manager(){}
	Manager(string name,string designation,double basic_pay,double DA,double HRA,double pay):Employee(name,designation,basic_pay,DA,HRA){
		this->pay=pay;
	}
	~Manager(){}
	double calculateSalary(){
		return Employee::calculateSalary()+pay;
	}
	void display(){
		Employee::display();
		cout<<"Manager pay: "<<pay<<"\n";
	}
};


class Worker:public Employee{
private:
	double allowances;
public:
	//Constructor
	Worker(){}
	Worker(string name,string designation,double basic_pay,double DA,double HRA,double allowances):Employee(name,designation,basic_pay,DA,HRA){
		this->allowances=allowances;
	}
	~Worker(){}
	double calculateSalary(){
		return Employee::calculateSalary()+allowances;
	}
	void display(){
		Employee::display();
		cout<<"Manager pay: "<<allowances<<"\n";
	}
};


int main (){
	Manager manager("Mary Clark","Operator",1500,50,50,150);
	Worker worker("Mike Smith","Programmer",2500,150,150,550);


	manager.display();
	cout<<"Salary: "<<manager.calculateSalary()<<"\n\n";


	worker.display();
	cout<<"Salary: "<<worker.calculateSalary()<<"\n\n";


	system("pause");
	return 0;
