Question
I am completely lost with this assignment.
For this assignment you will design a set of classes that work together to stimulate a police officer issuing a parking ticket. The classes you should design are:
- To know the car's make, model, color, license number, and the number of minutes that car has been parked.
- To know the number of minutes of parking time that has been purchased.
The ParkingTicket Class: This class should simulate a parking ticket. The class’s responsibilities are:
- To report the amount of the fine, which is $25 for the first hour or part of an hour that the car is illegally parked, plus $10 for every additional hour or part of an hour that the car is illegally parked.
- To report the name and badge number of the police officer issuing the ticket.
The PoliceOfficer Class: This class should simulate a police officer inspecting parked cars. The class’s responsibilities are:
- To examine a ParkedCar object and a ParkingMeter object, and determine whether the car’s time has expired.
-To issue a parking ticket(generate a ParkingTicket object) if the car's time has expired.
Write a program that demonstrates how these classes collaborate.
I have to submit each class seperately.
ParkedCar.h
ParkingMeter.h
ParkingTicket.h
PoliceOfficer.h
