// Tutorial 10: WageCalculator.cpp
// This application inputs the hourly wage and number of hours
// worked for an employee, then calculates the employee's gross 
// wages (with overtime for hours worked over 40 hours).
#include <iostream> // required to perform C++ stream I/O 
#include <iomanip>  // required for parameterized stream manipulators

using namespace std; // for accessing C++ Standard Library members

// calculate and display wages
double calculatePay( double hours, double wages )
{
   double total; // gross wages for a week

   // constant for maximum hours an employee can  
   // work before being paid for overtime
   const double HOUR_LIMIT = 40.0; 
   
   // determine gross wages
   if ( hours <= HOUR_LIMIT )
   {
      // regular wages for HOUR_LIMIT (40) hours or less
      total = wages * hours;
   } // end if
   else // worked more than HOUR_LIMIT (40) hours
   {
      // wages for first 40 hours with time and a half added
      total = ( wages * HOUR_LIMIT ) + ( hours - HOUR_LIMIT ) *
         ( 1.5 * wages );
   } // end else

   return total; // return the total wages earned
   
} // end function calculatePay
   
// function main begins program execution
int main()
{
   // define variables
   double hourlyWage;  // stores hourly wage
   double hoursWorked; // stores hours worked

   // prompt the user for hourly wage
   cout << "\nEnter hourly wage: ";
   cin >> hourlyWage; // get hourly wage

   // prompt the user for hours worked this week
   cout << "Enter hours worked this week: ";
   cin >> hoursWorked; // get the number of hours worked this week

   // gross wages for week; returned from function calculatePay
