// Exercise 11.13: ParkingGarage.cpp
// Calculate charges for cars at parking garage.
#include <iostream> // required to perform C++ stream I/O
#include <iomanip>  // required for parameterized stream manipulators
#include <cmath>    // required to use the C++ math library functions

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

int main()
{
   // define variables
   double hour;                // number of hours for current car
   double charge;              // parking charge for current car
   double totalCharges = 0.0;  // total charges
   double totalHours = 0.0;    // total number of hours

   // set floating-point number format
   cout << fixed;

   // prompt user for and store hours parked
   cout << "\nEnter the hours parked for a car (0 to end): ";
   cin >> hour; // get hours parked

   // repeat while hour is greater than zero
   while ( hour > 0 ) {
      totalHours += hour;  // add current hours to total hours
      
      // calculate current car's parking charge
      charge = 0.00;

      // update total charges
      totalCharges += charge;

      // display charge for current car
      cout << "Charge: $" << setprecision( 2 ) << charge 
           << endl;

      cout << "\nEnter the hours parked for a car (0 to end): ";
      cin >> hour; // get hours parked
