// Tutorial 4: 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 to manipulate C++ I/O stream

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

// function main begins program execution
int main()
{
   // define variables to store input
   double hourlyWage;  // stores hourly wage
   double hoursWorked; // stores hours worked

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

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

   // constant for maximum hours employee can
   // work before being paid for overtime
   const double HOUR_LIMIT = 40.0;

   // gross wages for week; calculated in if...else statement
   double wages;

   // determine gross wages
   if ( hoursWorked <= HOUR_LIMIT )
   {
      // regular wages for HOUR_LIMIT (40) hours or less
      wages = ( hoursWorked * hourlyWage );
   } // end if
   else // worked more than HOUR_LIMIT (40) hours
   {
      // wages for first HOUR_LIMIT (40) hours
      wages = HOUR_LIMIT * hourlyWage;

      // add time-and-a-half for overtime hours
      wages +=
         ( hoursWorked - HOUR_LIMIT ) * ( 1.5 * hourlyWage );
   } // end else

   // specify output format
   cout << fixed << setprecision( 2 );
   
   // display gross wages
   cout << "\nGross wages: $" << wages << endl << endl;

   return 0; // indicate that program ended successfully

} // end function main
