AIM: Design, develop, and execute a program in C++ based on the following requirements:

in EMPLOYEE class is to contain the following data members and member functions:

Data members: Employee_Number (an integer), Employee_Name (a string of characters),Basic_Salary (an integer) , All_Allowances(an integer), IT (an integer), Net_Salary (an integer).

Member functions: to read the data of an employee,to calculate Net_Salary and to print the values of all the data members.

(All_Allowances = 123% of Basic; Income Tax (IT) = 30% of the gross salary (= basic_Salary _ All_Allowance), Net_Salary = Basic_Salary + All_Allowances � IT)

THEORY:

CREATE an employee class and insert the data members and member function. That is,

Data members: Employee_Number (an integer), Employee_Name (a string of characters),Basic_Salary (an integer) , All_Allowances(an integer), IT (an integer), Net_Salary (an integer).

Member functions: to read the data of an employee,to calculate Net_Salary and to print the values of all the data members.

(All_Allowances = 123% of Basic; Income Tax (IT) = 30% of the gross salary (= basic_Salary _ All_Allowance), Net_Salary = Basic_Salary + All_Allowances � IT)

ALGORITHM:

1. start
2. create the class employee.
3. create the functions getdata,display,cal_sal and getnum.
4. end

CODE: emp.cpp

#include<iostream>
using namespace std;

class employee
{
    char name[15];
    int id;
    float basic,sal,netsal,da,it;

public:
            void getdata();
            void display();
            float cal_sal();
            int getnum();
};

void employee::getdata()
{
    cout<<" ID : ";
    cin>>id;

    cout<<" Name : ";
    cin>>name;

    cout<<" Basic Salary : ";
    cin>>basic;
}

void employee::display()
{


    cout.width(5);

    cout<<"id:"<<id;
    cout.width(15);
    cout<<"name:"<<name;
    cout.width(10);
    cout<<"basic:"<<basic;
    cout.width(10);
    cout<<"it:"<<it;
    cout.width(10);
    cout<<"da:"<<da;
    cout.width(10);
    cout<<"netsal:"<<netsal;

}

int employee::getnum()
{
    return id;
}

float employee::cal_sal()
{
    da = 1.23 * basic;
    sal = da + basic;
    it = 0.30 * sal;
    netsal = sal - it;
}


int main()
{
    short int i,j,n;
    employee emp[20];

    cout<<"Enter the number of Employees : ";
    cin>>n;

    for(i=0;i<n;i++)
    {
            emp[i].getdata();
            emp[i].cal_sal();
            emp[i].display();
}
return 0;
}

Output:

Enter the number of Employees : 1

ID : 1

Name : ram

Basic Salary : 10000

id:1
name:ram
basic:10000
it:6690
da:12300
netsal:15610
