Question

Payroll Application

Problem Description:

An org needs a payroll application which has the capability to calculate and print the monthly pay of an employee. The application starts by printing a short description of what it does. Then, it asks for the employee name. Next, the application prompts for employee type (“H” for hourly and “S” for salaried.) If the user enters S, the gross pay is set to $4000. However, if the user enters H for an hourly employee, the application asks for the number of hours worked and the hourly rate and these are used to calculate the gross pay.

The deductions from the paycheck before tax cuts are contributions to health insurance ($300) and retirement plan (6%). The federal income tax (15%) and state income tax (5%) are deducted after the contributions to health and retirement are deducted from the gross pay. A sample payslip for each kind of employee is shown in the screenshots below. Make sure your application’s output is similar or better than the screenshots given below.

Technical Specifications

• You should explain your code by providing adequate commenting.
• You will need two class files for this application. One will be called Payroll and the other PayrollTest.
• The program must ask for the name, and the employee type. The name and employee type should be stored as instance variables with appropriate properties. You will also need another instance variable to store the Gross Pay of the employee. The value for this variable will depend on the type of employee. If the employee is an hourly employee it should ask for the number of hours worked, and the hourly rate for the employee to calculate the gross pay.
• The program must then process the information and output it as shown in the samples above. All processing of the Net Pay will be done by a method in the Payroll class.
• All output must be printed by a method in the Payroll class. The output must print:
  • Payslip Header
  • The Gross Pay amount (rounded to two decimal places)
  • The contributions to health and retirement plans and the federal and state tax amounts.
  • And finally, the net pay amount (rounded to two decimal places)

Answer 1

ANSWER:

Here a new Console Application in C# is created using Visual Studio 2017 with name "PayrollApplication".This application conatins class "Payroll.cs" and one test class for testing payroll class that is "PayrollTest.cs".Below is the details about these classes.

Payroll.cs :

//namespaces
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
//application namespace
namespace PayrollApplication
{
//class Payroll
class Payroll
{
//property name
public string Name { get; set; }
//Employee Type
public string EmployeeType { get; set; }
//Gross Pay
public double GrossPay { get; set; }

//method to calculate details
public void calculateNetPay(double grossPay)
{
//health contribution
double helathInsuranceContribution = 300;
//retirement contribution
double retirementContribution=(grossPay * 6) / 100;
//Amount for tax deductions
double amountForTaxDeduction = grossPay - 300 - retirementContribution;
//Federal Income Tax
double federalIncomeTax = amountForTaxDeduction * 15 / 100;
//State Income Tax
double stateIncomeTax = amountForTaxDeduction * 5 / 100;
Console.WriteLine("***************************************");
//printing payslip details
Console.WriteLine($"PAY SLIP FOR : {Name} , MONTH : {DateTime.Now.Month}, {DateTime.Now.Year}");
Console.WriteLine("***************************************");
//display employee type
Console.WriteLine($"Employee Type :{EmployeeType}");
Console.WriteLine($"Monthly Gross Pay : {grossPay.ToString("0.00")} ");
Console.WriteLine("-------------------------------------------");
//display monthly contrbutions
Console.WriteLine("MONTHLY CONTRIBUTIONS");
Console.WriteLine($"Helath : {helathInsuranceContribution} Retirement : {retirementContribution} ");
Console.WriteLine("-------------------------------------------");
//display taxes
Console.WriteLine("TAX DEDUCTIONS");
Console.WriteLine($"Amount on which Tax Deducted : {amountForTaxDeduction} ");
Console.WriteLine($"Federal Income Tax : {federalIncomeTax}, State Income Tax : {stateIncomeTax}");
Console.WriteLine($"============================================ ");
//display net pay
Console.WriteLine($"NET PAY : {(amountForTaxDeduction- federalIncomeTax- stateIncomeTax).ToString("0.00")} ");

}
}
}

**********************************

PayrollTest.cs :

//namespaces
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
//application namespace
namespace PayrollApplication
{
//class PayrollTest
class PayrollTest
{
//Main Method
static void Main(string[] args)
{
//creating Payroll Object
Payroll payroll = new Payroll();
//asking user to enter employee name
Console.WriteLine("Enter Employee Name : ");
//Reading Employee Name
payroll.Name = Console.ReadLine();
//askin employee type
Console.WriteLine("Enter Employee Type (“H” for hourly and “S” for salaried.) : ");
//reading employee Type
payroll.EmployeeType = Console.ReadLine();
//checking employee type
if(payroll.EmployeeType=="S")
{
//if salaried employee
payroll.GrossPay = 4000;
//calling method to calculate taxes and contributions and print pay slip
payroll.calculateNetPay(payroll.GrossPay);
}
else if (payroll.EmployeeType == "H")
{
//if Hourly employee
//asking user number of hours worked
Console.WriteLine("Enter Number of Hours Worked : ");
//reading hours
double hours = double.Parse(Console.ReadLine());
//asking user hourly rate
Console.WriteLine("Enter Hourly Rate : ");
//reading hourly rate
double hourlyRate = double.Parse(Console.ReadLine());
//calculating gross pay
payroll.GrossPay = hours*hourlyRate;
//calling method to calculate taxes and contributions and print pay slip
payroll.calculateNetPay(payroll.GrossPay);
}
//to hold the screen
Console.ReadKey();

}
}
}

======================================================

Output : Run application using F5 and will get the screen as shown below

Screen 1 :Screen asking Employee Name

Screen 2 :Screen asking Employee Type

Screen 3 :Screen showing payslip for Salaried Employee

Screen 4 :Screen showing payslip for Hourly Employee
