Question

Has to be written in C#! Write a program that includes an Employee class that can be used to calculate and print the take-home pay for a commissioned sales employee. Items to include as data members are employee number, first name, last name, and total sales. All employees receive 9% of the total sales of the month. Federal tax rate is 18%. Retirement contribution is 10%. Social Security tax rate is 6%. Use appropriate constants, design an object-oriented solution, and write constructors. Include at least one mutator and one accessor method; provide properties for the other data members. Create a second class, or a driver program, to test your design. Allow the user to enter values for the name of the employee and the sales amount for the month in the driver program as “Mike”, “Johnson”, and $50,000.

C# Program:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace commissionedSalesEmployee
{
    //Class definition
    class Employee
    {
        //Member Variables
        private int empNumber;
        private String fName;
        private String lName;
        private double totalSales;

        public const int FederalTaxRate = 18;
        public const int RetirementContribution = 10;
        public const int SocialSecurityTaxRate = 6;

        //Default Constructor
        public Employee()
        {
            empNumber = 0;
            fName = "";
            lName = "";
            totalSales = 0.0;
        }

        //Parameterized constructor
        public Employee(int eNo, String efName, String elName, double sales)
        {
            empNumber = eNo;
            fName = efName;
            lName = elName;
            totalSales = sales;
        }

        //Setter methods
        public void setFirstName(String efName)
        {
            fName = efName;
        }

        //Getter methods
        public void setLastName(String elName)
        {
            lName = elName;
        }

        //Setter methods
        public void setEmpNo(int eNo)
        {
            empNumber = eNo;
        }

        //Setter methods
        public void setSales(double sales)
        {
            totalSales = sales;
        }

        //Getter method
        public int getEmpNo()
        {
            return empNumber;
        }

        //Getter method
        public String getfName()
        {
            return fName;
        }

        //Getter method
        public String getlName()
        {
            return lName;
        }

        //Getter method
        public double getSales()
        {
            return totalSales;
        }

        public double computeTakeHomePay()
        {
            double pay;

            //9% of total sales
            pay = (9 / 100.0) * totalSales;

            //Federal tax rate is 18%
            pay = pay - (pay * (FederalTaxRate / 100.0));

            //Retirement Contribution is 10%
            pay = pay - (pay * (RetirementContribution / 100.0));

            //Social security tax rate is 18%
            pay = pay - (pay * (SocialSecurityTaxRate / 100.0));

            return pay;
        }
    }
  
    //Driver class
    class Program
    {
        //Main method
        static void Main(string[] args)
        {
            //Creating employee object
            Employee emp = new Employee(123, "Mike", "Johnson", 50000);

            //Printing Employee details
            Console.WriteLine("\n Employee Number: " + emp.getEmpNo().ToString());
            Console.WriteLine("\n First Name: " + emp.getfName());
            Console.WriteLine("\n Last Name: " + emp.getlName());
            Console.WriteLine("\n Total Sales: $" + emp.getSales().ToString());
            Console.WriteLine("\n\n Take Home Pay: $" + emp.computeTakeHomePay().ToString() + " \n\n");

            Console.ReadKey();
        }
    }
}
