Calculations no processing C++ - c++

Question

I'm making a simple payroll calculator and for some reason my "taxes" aren't calculating. When I run the program they just show $0 in the output. Any idea whats causing this? I commented "// Not calculating. Shows $0" on the lines that aren't calculating.
#include <iostream>
using namespace std;
int main()
// Parameters: None
// Returns: Zero
// Calls: None
{
int const hourly_wage = 16.78, overtime_rate = 25.17, social_security = 0.06, federal_income = 0.14, state_income = 0.05, union_dues = 10;
int gross_pay, hours_worked, number_of_dependents, ss_withheld, federal_withheld, state_withheld, net_pay, insurance, overtime_pay, again;
cout << "This program will calculate payroll for an employee." << endl;
do
{
cout << "\n\nEnter the number of hours the employee worked: " << endl;
cin >> hours_worked;
if (hours_worked > 40) {
overtime_pay = (hours_worked - 40) * overtime_rate;
gross_pay = (40 * hourly_wage) + overtime_pay;
}
else {
gross_pay = hours_worked * hourly_wage;
}
cout << "\n\nEnter the number of dependents for employee: " << endl;
cin >> number_of_dependents;
if (number_of_dependents >= 3) {
insurance = 35;
}
else {
insurance = 0;
}
// Payroll Calculation
ss_withheld = gross_pay * social_security;
federal_withheld = gross_pay * federal_income;
state_withheld = gross_pay * state_income;
net_pay = gross_pay - (ss_withheld + federal_withheld + state_withheld + insurance + union_dues);
cout << "\n\nGross Pay: $" << gross_pay << endl;
cout << "Social Security Withhholding: $" << ss_withheld << endl; // Not calculating. Shows $0
cout << "Federal Withholding: $" << federal_withheld << endl; // Not calculating. Shows $0
cout << "State Withholding: $" << state_withheld << endl; // Not calculating. Shows $0
cout << "Union Dues: $" << union_dues << endl;
cout << "Insurance Deduction: $" << insurance << endl;
cout << "Net Pay: $" << net_pay << endl;
cout << "\nDo you want to do another employee(Y/N)? ";
cin >> again;
} while (again == 'y' || again == 'Y');
cout << "\nHope they enjoy the money!" << endl;
return 0;
}

It looks like you are creating int Const for double values. ie.
#include "stdafx.h";
#include <iostream>
using namespace std;
int main()
// Parameters: None
// Returns: Zero
// Calls: None
{
int const union_dues = 10;
double const hourly_wage = 16.78, overtime_rate = 25.17, social_security = 0.06, federal_income = 0.14, state_income = 0.05;
double gross_pay, hours_worked, number_of_dependents, ss_withheld, federal_withheld, state_withheld, net_pay, insurance, overtime_pay, again;
cout << "This program will calculate payroll for an employee." << endl;
do {
cout << "\n\nEnter the number of hours the employee worked: " << endl;
cin >> hours_worked;
if (hours_worked > 40) {
overtime_pay = (hours_worked - 40) * overtime_rate;
gross_pay = (40 * hourly_wage) + overtime_pay;
}
else {
gross_pay = hours_worked * hourly_wage;
}
cout << "\n\nEnter the number of dependents for employee: " << endl;
cin >> number_of_dependents;
if (number_of_dependents >= 3) {
insurance = 35;
}
else {
insurance = 0;
}
// Payroll Calculation
ss_withheld = gross_pay * social_security;
federal_withheld = gross_pay * federal_income;
state_withheld = gross_pay * state_income;
net_pay = gross_pay - (ss_withheld + federal_withheld + state_withheld + insurance + union_dues);
cout << "\n\nGross Pay: $" << gross_pay << endl;
cout << "Social Security Withhholding: $" << ss_withheld << endl; // Not calculating. Shows $0
cout << "Federal Withholding: $" << federal_withheld << endl; // Not calculating. Shows $0
cout << "State Withholding: $" << state_withheld << endl; // Not calculating. Shows $0
cout << "Union Dues: $" << union_dues << endl;
cout << "Insurance Deduction: $" << insurance << endl;
cout << "Net Pay: $" << net_pay << endl;
cout << "\nDo you want to do another employee(Y/N)? ";
cin >> again;
} while (again == 'y' || again == 'Y');
cout << "\nHope they enjoy the money!" << endl;
return 0;
