Question

An employee is paid at a rate of $16.78 per hour for regular hours worked in a week. Any hours over that are paid at the overtime rate of 1.5 times that. From the worker's gross pay, 6% is withheld for social security tax, 14% is withheld for federal income tax, 5% is withheld for state income tax, and $10 per week is withheld for union dues. If the worker has three or more dependents, then an additional $35 is withheld to cover the extra cost of health insurance beyond what the employer pays. Write a C++ program that will read in the number of hours worked in a week and the number of dependents as input, and will then output the worker's gross pay, each withholding amount, and the net take-home pay for the week. Your program should allow the calculation to be repeated as often as the user wishes.

Part 1

Like we did for 'Practice 1' in this course note, divide this task into several subtasks. Some of subtasks may be divided into a few sub-subtask.

• State subtasks/sub-subtasks as comments in C++ code.

Part 2

Write a C++ code to do this task taking steps you define at Part 1.

• The regular work hours is 40 hours a week.
• Declare variables to express all constant values used in the code with the modifier const.
  • For example,

  • const double pay_rate_per_hour=16.78;

• Use appropriate data type for each variable.
• Amounts in dollar should be formatted; show 2 digits of fraction part to represent the cent, like $456.20.

Answer 1

Here is the code for the problem.

I have provided comments for your understanding.

I have created subtasks and sub-subtasks as mentioned.

#include <bits/stdc++.h>

using namespace std;

// declaring constants

const double pay_rate_per_hour = 16.78;

const double overtime_rate = pay_rate_per_hour * 1.5;

const double social_security_tax_percent = 0.06;

const double federal_income_tax_percent = 0.14;

const double state_income_tax_percent = 0.05;

const int union_dues = 10;

const int health_insurance = 35;

const int regular_work_hours = 40;

const int number_of_dependents = 3;

// subtask : calculating pay

double pay_without_deductions(int hours)

{

    if (hours <= regular_work_hours)

    {

        return (hours * pay_rate_per_hour);

    }

    else

    {

        return (regular_work_hours * pay_rate_per_hour + (hours - regular_work_hours) * overtime_rate);

    }

}

// sub-subtask : calculating taxes

double calculate_social_security_tax(double total_pay)

{

    return (total_pay * social_security_tax_percent);

}

// sub-subtask : calculating taxes

double calculate_federal_income_tax(double total_pay)

{

    return (total_pay * federal_income_tax_percent);

}

// sub-subtask : calculating taxes

double calculate_state_income_tax(double total_pay)

{

    return (total_pay * state_income_tax_percent);

}

// subtask : deducting taxes

double deduct_all_deus(double total_pay, int dependents)

{

    // calculating taxes using functions

    double social_security_tax = calculate_social_security_tax(total_pay);

    double federal_income_tax = calculate_federal_income_tax(total_pay);

    double state_income_tax = calculate_state_income_tax(total_pay);

    // subtarcting taxes

    total_pay -= (social_security_tax + federal_income_tax + state_income_tax);

    // subtracting union dues

    total_pay -= union_dues;

    // subtracting health insurance if dependents greater than 3

    if (dependents >= number_of_dependents)

    {

        total_pay -= health_insurance;

    }

    return total_pay;

}

int main()

{

    // calling function any number of times

    while (true)

    {

        // taking inputs

        int hours, dependents;

        cout << "Enter Number of Hours worked this Week:\t";

        cin >> hours;

        cout << "Enter Number of Dependents:\t";

        cin >> dependents;

        // calculating pay

        double gross_pay = pay_without_deductions(hours);

        gross_pay = deduct_all_deus(gross_pay, dependents);

        // printing result

        cout << "Gross Pay:\t" << fixed << setprecision(2) << gross_pay << endl;

        // asking user to continue

        int ans;

        cout << "Do you want to continue(1 = yes, 0 = no):\t";

        cin >> ans;

        if (ans != 1)

        {

            break;

        }

    }

    return 0;

}

Here are the screenshot of the code if the indentation is not clear.

Here is the screenshot of the output.

Hope this helps.
