Use parameterized constructor in the derived class(calc gross and net pay of employee in derived class)

11. 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.

#include<iostream.h>

#include<string.h>

class employee

{

    protected:

                int id,basic;                    

                char name[20];

    public:

                employee(int i,char *s,int b)

                    {

                        id=i;    

                        strcpy(name,s);         

                        basic=b;

                    }

                void show()

                    {

                        cout<<"\nEmp. Id: "<<id<<"\n";

                        cout<<"Emp. Name: "<<name<<"\n";

                        cout<<"Basic Salary: "<<basic<<"\n";

                    }

};

class grossnet: public employee

{

            float deduct,gross,net;

            public:

                        grossnet(int i,char *s, int b,int d,float g,float n): employee(i,s,b)

                        {

                                    deduct=d;      gross=g;         net=n;

                        }

                        void calculate();

};

void grossnet::calculate()

{

    float da,hra;

    da=0.4*basic;

    hra=0.2*basic;

    gross=basic+da+hra;

    net=gross-deduct;

    cout<<"Gross Pay: "<<gross<<"\n";

    cout<<"Net Pay: "<<net<<"\n";

}

void main()

{

    int eid,ebasic;

    float ededuct;

    char ename[20];

    cout<<"Enter:\n";

    cout<<"Employee Id: ";                  

    cin>>eid;

    cout<<"Employee Name: ";           

    cin>>ename;

    cout<<"Basic Salary: ";    

    cin>>ebasic;

    cout<<"Deductions: ";      

    cin>>ededuct;

    grossnet gn(eid,ename,ebasic,ededuct,0,0);

    gn.show();

    gn.calculate();

}

OUTPUT:

Enter:

Employee Id: 123

Employee Name: Lahari

Basic Salary: 10000

Deductions: 1450.0

Emp. Id: 123

Emp. Name: Lahari

Basic Salary: 10000

Gross Pay: 16000

Net Pay: 14550
