Question

Using C++. For this assignment you will design a set of classes that work together to simulate a police officer issuing a parking ticket. The classes you should design are :

The ParkedCar class: This class should simulate a parked car. The class's responsibilities are:

-to know the car's make, model,color ,license number,and the number of minutes that the car has been parked

The ParkingMeter Class: This class should simulate a parking meter. the class's only responsibility is:

-To know the number of minutes of parking time that has been purchased.

The ParkingTicket Class: This clas should simulate a aprking ticket. The class's responsibilities are:

-To report the make, model, color, and license number of the illegally parked car

-To report the amount of the fine,which is $25 for the first hour or part of an hour that the car is illegal 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. This class's responsibilities are:

-To know the police officer's name and badge number

-To examine a ParkedCar object and a ParkingMeter object, and determine whether the car's time expired

-To issue a parking ticket (generate a ParkingTicket object) if the car's time has expired

Write a program that demonstrates how these collaborate.

Answer 1

Below is the program for the above question statement. Go through the program and the comments to better understand the program flow and logic.

//Program to to simulate a police officer issuing a parking ticket

#include <iostream>
using namespace std;

class ParkedCar{
   //car's make, model,color ,license number,and the number of minutes that the car has been parked
   //Access specifier
    public:

    // Data Members
    string make;
    string model;
    string color;
    string license_number;
    int parked_minutes;

   };

class ParkingMeter{
   //To know the number of minutes of parking time that has been purchased.
   //Access specifier
    public:

    // Data Member
    int parking_minutes_purchased;
   };

class ParkingTicket {
   //Access specifier
    public:
  
   //To report the make, model, color, and license number of the illegally parked car
    void printcardetails(ParkedCar pc)
    {
        cout << "Car's make, model, color, and license number is given below:\n" ;
        cout << pc.make <<"\n";
        cout << pc.model<<"\n";
        cout << pc.color<<"\n";
        cout << pc.license_number<<"\n";
    }
  
   //To report the amount of the fine,which is $25 for the first hour or part of an hour that the car is illegal parked, plus $10 for every additional hour or part of an hour that the car is illegally parked
   void printfine(ParkedCar pc, ParkingMeter pm)
   {   int fine = 0;
       //calculate the fine when illegal parked time is less than or exactly one hour
       int extratime = pc.parked_minutes - pm.parking_minutes_purchased;
       if(extratime<=60)
       {
               fine = 25;
       }
       else
       { //when illegal parked time is more than an hour
               fine = 25;
               extratime = extratime - 60;
               //for every additional hour plus $10
               while(extratime>0){
                   fine = fine + 10;
                   extratime = extratime - 60;
                   }
       }

   //To report the name and badge number of the police officer issuing the ticket
   void printofficerdetail(string name,int number)
   {
       cout << "Officer's name : " << name;
       cout <<"\n";
       cout << "Officer's Badge number : " << number;  
       cout <<"\n";  
   }
};

class PoliceOfficer : public ParkingTicket{
   //Access specifier
    public:

    // Data Members
   //To know the police officer's name and badge number
   string officername;
   int badge_number;
  
   //To examine a ParkedCar object and a ParkingMeter object, and determine whether the car's time expired
   int examineparkedcar(ParkedCar pc, ParkingMeter pm){
       if(pc.parked_minutes <= pm.parking_minutes_purchased)
       {
           return 1;
       }
       else
           return 0;
      
       }
   //To issue a parking ticket (generate a ParkingTicket object) if the car's time has expired
   void generateticket(ParkedCar pc, ParkingMeter pm)
   {   //create an objectof Paring ticket class
       ParkingTicket pt;
       //generate the parking ticket
       pt.printcardetails(pc);
       pt.printfine(pc,pm);
       pt.printofficerdetail(officername,badge_number);
   }
};

int main()
{   
   //create object for parked car class
   ParkedCar pc;
   pc.make = "Honda";
   pc.model = "Accord";
   pc.color = "White";
    pc.license_number = "XYZ11111";
    pc.parked_minutes = 180;
    //create object for parking meter class
    ParkingMeter pm;
    pm.parking_minutes_purchased= 60;
    //create object for policeofficer class
    PoliceOfficer po;
    po.officername = "John";
    po.badge_number = 1111;
  
    //determine whether the car's time expired
    if(po.examineparkedcar(pc,pm))
    {
       cout << "Time not expired.Fine is Zero!" ;
   }
   else
   {
       cout << "Time Expired .\n" ;
       po.generateticket(pc,pm);
   }

    return 0;
}
