Answer to Question #329696 in C++ for Abishek

Question

Write a program to calculate gross and net pay of employee from basic salary. Create employee class which consists of employee name, emp_id, and basic salary as its data members. Use parameterized constructor in the derived class to initialize data members of the base class and calculate gross and net pay of the employee in the derived class.

Answer 1

#include<iostream>
#include<string>

using namespace std;

class Employee
{
	string name;
	int emp_id;
	double basic_sal;
protected:
	Employee(string _name,int _emp_id, double _basic_sal)
	:name(_name), emp_id(_emp_id), basic_sal(_basic_sal){}
	void DisplayEmployee()
	{
		cout << "\nName of employee is " << name
			<< "\nEmployee ID of employee is " << emp_id
			<< "\nBasic salary of employee is " << basic_sal;
	}
	double GetSalary() { return basic_sal; }
};


class Calculate:public Employee
{
	double gross_pay;
	double net_pay;
public:
	Calculate(string _name,	int _emp_id, double _basic_sal)
	:gross_pay(0), net_pay(0),Employee(_name, _emp_id, _basic_sal){}
	void CalculateGross()
	{
		float suppl;
		cout << "Please, enter salary supplements (from 1 to 40): ";
		cin >> suppl;
		gross_pay = suppl*GetSalary()+GetSalary();
	}
	void CalculateNet()
	{
		float taxes;
		cout << "Please, enter share of taxes (from 1 to 40): ";
		cin >> taxes;
		net_pay = gross_pay-(gross_pay*taxes / 100);
	}
	void Display()
	{
		DisplayEmployee();
		cout << "\nGross salary is " << gross_pay
			<< "\nNet pay is " << net_pay;
	}
};

int main()
{
	Calculate a("Jack", 1234, 3000);
	a.CalculateGross();
	a.CalculateNet();
	a.Display();
}
