C# that has multiple methods but uses parameter types

Create a program that still has many methods but uses the parameter types
listed below. The program
should be written so it takes input for employee name, hours worked and
hourly rate of pay, and then determines an employees gross pay, State tax,
Federal tax, FICA tax, and net pay using the formulas underneath. Calculations for gross pay, State tax,
Federal tax, FICA tax, and net pay need to be done in separate
methods (5 methods in addition to the Main method). Calculation of gross pay needs to be done in a
method that uses two value parameters and returns the gross pay. Calculation of State Tax should be done in a
void method that uses an output parameter for State Tax and a value parameter
for the gross pay. Other methods should be
void and use reference parameters. Again,
do not use any global variables.

Gross pay = hours worked times
hourly rate of pay

State tax = Gross pay times 0.02

Federal tax = Gross pay
times 0.20

FICA tax = Gross pay times
0.19

Net pay = Gross pay minus
(State tax +FICA tax + Federal tax )

Print a prompt message for each input item
telling the user what to enter and then accept values for variables named
hoursWorked and payRate. Loop until 'Quit' is entered for
the employee's name.

This question is very similar to the one you asked on the VB.NET forum and which has now mysteriously disappeared:

Only minor changes are therefore required:

using System;

class Program

{

static void Main()

{

while(true)

{

Console.Write("Enter Employee name or 'Quit' to quit : ");

string name = Console.ReadLine();

if (name == "Quit") return;

double hoursWorked;

double payRate;

while(true)

{

Console.Write("Enter Hours Worked : ");

bool isValid = Double.TryParse(Console.ReadLine(), out hoursWorked);

if (isValid) break;

Console.WriteLine("Not a valid number. Please try again");

}

while(true)

{

Console.Write("Enter Hourly Rate of Pay : ");

bool isValid = Double.TryParse(Console.ReadLine(), out payRate);

if (isValid) break;

Console.WriteLine("Not a valid number. Please try again");

}

Console.WriteLine();

double grossPay = CalculateGrossPay(hoursWorked, payRate);

Console.WriteLine("Gross pay = {0:C}", grossPay);

double stateTax;

CalculateStateTax(grossPay, out stateTax);

Console.WriteLine("State tax = {0:C}", stateTax);

double federalTax = 0;

CalculateFederalTax(ref grossPay, ref federalTax);

Console.WriteLine("Federal tax = {0:C}", federalTax);

double FICATax = 0;

CalculateFICATax(ref grossPay, ref FICATax);

Console.WriteLine("FICA tax = {0:C}", FICATax);

double netPay = 0;

CalculateNetPay(ref grossPay, ref stateTax, ref federalTax, ref FICATax, ref netPay);

Console.WriteLine("Net pay = {0:C}", netPay);

Console.WriteLine();

}

static double CalculateGrossPay(double hoursWorked, double payRate)

{

return Math.Round(hoursWorked * payRate, 2);

}

static void CalculateStateTax(double grossPay, out double stateTax)

{

stateTax = Math.Round(grossPay * 0.04, 2);

}

static void CalculateFederalTax(ref double grossPay, ref double federalTax)

{

federalTax = Math.Round(grossPay * 0.23, 2);

}

static void CalculateFICATax(ref double grossPay, ref double FICATax)

{

FICATax = Math.Round(grossPay * 0.14, 2);

}

static void CalculateNetPay(ref double grossPay, ref double stateTax, ref double federalTax, ref double FICAtax, ref double netPay)

{

netPay = Math.Round(grossPay - (stateTax + federalTax + FICAtax), 2);

}
