Question

C PROGRAM ..... NOT C++

PROGRAM 3 (UPDATE TO TWO PRIOR PROGRAMS FOR REFERENCE OF PRIOR PROGRAM INSTRUCTIONS PLEASE SEE BELOW)

PROGRAM 3

Adjust program II to make use of functions. All the same rules from the previous program specifications still apply, for example input gathering, output formatting and breaking on -1 still apply.

Additional requirements.

• Write a function that prompts the user for hours worked, rate and name. Use parameter passing, and pass by reference.
• Write a function that calculates the gross, base and overtime pay, pass by reference.
• Write a function 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 function that calculates the gross pay.
• Write a print function 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.)

PROGRAM 1 AND 2 (JUST FOR REFERENCE NO CODE NEEDED)

PROGRAM 1

Payroll application

1. Write a program that reads in the first name, hourly rate and number of hours worked for 5 people.
2. Print the following details for each employee.
   1. Name of employee
   2. The number of hours worked
   3. Their weekly gross pay
      1. This is calculated by multiplying hours worked times hourly rate.
         1. If hours worked per week is greater than 40, then overtime needs to also be included.
            1. Overtime pay is calculated as the number of hours worked beyond 40 * rate * 1.5
   4. Taxes withheld
      1. Our tax system is simple, the government gets 20% of the gross pay.
   5. Net paid
      1. The amount of the check issued to the employee.

PROGRAM 2

Payroll 2.0

Update the first program.

1. Use for loops to process the data for 5 employees.
   1. One loop to load the data
   2. One loop to print the output.
   3. In for loops, if any of the entered fields are –1, break out of the loop immediately after getting -1
2. Update the output as shown in the sample data.
3. Use arrays to store the user input.

The program logic will first load all of the data, until the user enters the max number of records, or they input -1 for one of the fields. After the data is loaded, it will then be processed and output generated.

CODE USED FOR PROGRAM 2:

#include <stdio.h>
#include <string.h>
void main()
{
char name[5][30];
float hourly_rate[5], hours_worked[5];
float n, gross;
for (int i = 0; i < 5; i++)
{
printf("\nEnter the first name: ");
scanf("%s", name[i]);
if (!strcmp(name[i], "-1"))
break;
printf("\nEnter the hourly rate: ");
scanf("%f", &hourly_rate[i]);
if (hourly_rate[i] == -1)
break;
printf("\nEnter the hours worked: ");
scanf("%f", &hours_worked[i]);
if (hours_worked[i] == -1)
break;
}
for (int i = 0; i < 5; i++)
{
if (!strcmp(name[i], "-1"))
break;
if (hourly_rate[i] == -1)
break;
if (hours_worked[i] == -1)
break;
printf("\nPay to: %s", name[i]);
printf("\nHours worked: %f", hours_worked[i]);
printf("\nHourly rate: $%f", hourly_rate[i]);
if (hours_worked[i] > 40)
{
n = hours_worked[i] - 40;
gross = (40 * hourly_rate[i]) + (n * hourly_rate[i] * 1.5);
printf("\nGross pay: $ %f", gross);
printf("\nBase pay: $ %f", 40 * hourly_rate[i]);
printf("\nOvertime pay: $ %f", n * hourly_rate[i] * 1.5);
printf("\nTax paid: $ %f", gross * .20);
printf("\nNet paid: $ %f", gross - (gross * .20));
}
else
{
printf("\nGross pay:$ %f", hourly_rate[i] * hours_worked[i]);
printf("\nBase pay: $ %f", hourly_rate[i] * hours_worked[i]);
printf("\nTax paid: $ %f", hourly_rate[i] * hours_worked[i] * .20);
printf("\nNet pay: $ %f", (hourly_rate[i] * hours_worked[i]) - (hourly_rate[i] * hours_worked[i] * .20));
}
}
}

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
=================================

#include <stdio.h>
#include <string.h>

// Function Declarations
float calcBasePay(float hours_worked,float hourly_rate);
float calcOverTimePay(float hours_worked,float hourly_rate);

{
   //Declaring variables
   int i;

for (i = 0; i < 5; i++)
{
printf("\nEnter the first name: ");
scanf("%s", name[i]);
if (!strcmp(name[i], "-1"))
break;

// Function which calculate Gross pay
