The program adjusts an existing payroll program to use methods. It writes methods to: 1. Prompt the user for an employee's hours worked, rate, and name and pass the values by reference. 2. Calculate gross, base, and overtime pay by passing values by reference. 3. Calculate tax by taking gross pay as input and returning the tax owed. 4. Print an output method that generates totals for all employees, including total amount paid.

1. Program Description Adjust program II to make use of methods. All the same rules from the
previous program specifications still apply, for example input gathering, output formatting and
breaking on -1 still apply. Write a method that prompts the user for hours worked, rate and name.
Use parameter passing, and pass by reference. Write a method that calculates the gross, base and
overtime pay, pass by reference. Write a method that calculates tax, taking as input the gross pay,
returning the tax owed. Calculate the total amount paid (gross pay) for all 5 people. Use the
return value from the method that calculates the gross pay. Write a print method that generates
the output, including the total amount paid, in addition to the data for each employee. Example
(Sample input & output for one person) Enter name: Glenn Enter hourly rate: 2.00 Enter hours
worked: 50 Enter name: -1 Pay to: Glenn Hours worked: 50.0 Hourly rate: $ 2.00 Gross pay:
$110.00 Base pay: $ 80.00 Overtime pay: $ 30.00 Taxes paid: $ 22.00 Net pay: $ 88.00 Total
Paid to all employees = $110.00 (The grand total of payments out.)
Solution
#include <stdio.h>
main()
{
char name[25];
float rate = 0;
float hours = 0;
float basePay = 0;
float overTime = 0;
float grossPay = 0;
float netPay = 0;

2. int i;
for(i = 0; i < 5; i++) {
printf(" What is your name? ");
scanf("%s", &name);
printf(" How much is your hourly pay? ");
scanf("%f", &rate);
printf(" How many hours did you work this week? ");
scanf("%f", &hours);
basePay = rate * hours;
grossPay = rate * 40 + (basePay - overTime);
overTime = (basePay - (1.5 * rate));
netPay = grossPay - (0.20 * grossPay);
if (hours > 40){
printf(" Pay for %s ", name);
printf(" Hourly rate:t $%.2f ", rate);
printf(" Hours worked:t $%.2f ", hours);
printf(" Gross pay:t $%.2f ", grossPay);
printf(" Taxes paid:t $%.2f ", 0.20 * grossPay);
printf(" Base pay:t $%.2f ", basePay);
printf(" Overtime pay:t $%.2f ", overTime);
printf(" Net pay:t $%.2f ", netPay);

3. }
else {
printf(" Pay for %s ", name);
printf(" Hourly rate:t $%.2f ", rate);
printf(" Hours worked:t $%.2f ", hours);
printf(" Gross pay:t $%.2f ", basePay);
printf(" Taxes paid:t $%.2f ", 0.20 * basePay);
printf(" Base pay:t $%.2f ", basePay);
printf(" Overtime pay:t $0.00 ");
printf(" Net pay:t $%.2f ", basePay -(basePay * 0.20));
}
}
