The programming challenge is to create a parking ticket simulator with 4 different classes, each has its own set of responsibilities. To keep things simple, I've only written ParkedCar, ParkingMeter and ParkingTicket.ParkedCar class holds the make, model, color, license number, and the number of minutes parked.
ParkingMeter class holds only the minutes purchased.
ParkingTicket needs to look at the ParkedCar object, and "read" those values, and possibly determine if a fine should be generated.
I've included the 3 header files, and also the main.
Could someone show me the correct syntax so that I need to code so that the ParkingTicket object "talks to" the ParkedCar object. It is this line where I'm confused. I would like the function getCarMake to read the data stored in ParkedCar::setMake function. Hopefully that makes sense. As always, I appreciate any assistance you can offer.
cout << ticket.getCarMake();
#include <iostream> #include <string> #ifndef PARKEDCAR #define PARKEDCAR using namespace std; class ParkedCar { private: string make; string model; string color; string licNum; int numMinParked; public: //constructor ParkedCar::ParkedCar() { make = ""; model = ""; color = ""; licNum = ""; numMinParked = 0; } //mutators void ParkedCar::setMake(string m) { make = m; } void ParkedCar::setModel(string mod) { model = mod; } void ParkedCar::setColor(string c) { color = c; } void ParkedCar::setLicNum(string l) { licNum = l; } void ParkedCar::setNumMinParked(int nmin) { numMinParked = nmin; } //accessors string ParkedCar::getMake(string m) { return make; } string ParkedCar::getModel()const { return model; } string ParkedCar::getColor()const { return color; } string ParkedCar::getLicNum()const { return licNum; } int ParkedCar::getNumMinParked()const { return numMinParked; } }; #endif;
#include <iostream> #include <string> #ifndef PARKINGMETER #define PARKINGMETER using namespace std; class ParkingMeter { private: int minPurchased; public: //constructor ParkingMeter::ParkingMeter() { minPurchased = 0; } //mutators void ParkingMeter::setMinPurchased(int m) { minPurchased = m; } //accessors int ParkingMeter::getMinPurchased()const { return minPurchased; } }; #endif;
#include <iostream> #include <string> #include "ParkingMeter.h" #include "ParkedCar.h" #ifndef PARKINGTICKET #define PARKINGTICKET using namespace std; class ParkingTicket { private: double fine; int parkedTime, timePurchased; string v; ParkedCar car; public: //constructor ParkingTicket() { fine = 0.0; parkedTime = 0; timePurchased = 0; //car.setMake(""); //car.setModel(""); //car.setColor(""); //car.setLicNum(""); } //mutators void setParkedTime(int t) { parkedTime = t; } void setFine(double f) { fine = f; } void setCarMake(string c) { car.setMake(c); } void setCarModel(string d) { car.setModel(d); } //accessors string getCarMake() { return car.getMake(); } int ParkingTicket::getParkedTime(int t) { return parkedTime; } }; #endif;
#include <iostream> #include <string> #include "ParkingTicket.h" #include "PoliceOfficer.h" #include "ParkedCar.h" #include "ParkingMeter.h" void myTitle(); int main() { myTitle(); system("pause"); system("cls"); string value; int num = 0; ParkedCar car; ParkingMeter meter; ParkingTicket ticket; PoliceOfficer donutman; cout << "What is the make of the car?\n"; cin >> value; car.setMake(value); cout << "What is the model of the car?\n"; cin >> value; car.setModel(value); cout << "What is the color of the car?\n"; cin >> value; car.setColor(value); cout << "What is the license plate number?\n"; cin >> value; car.setLicNum(value); cout << "How many minutes were purchased for this parking spot?\n"; cin >> num; meter.setMinPurchased(num); cout << "How many minutes has this vehicle been parked?\n"; cin >> value; car.setNumMinParked(num); cout << ticket.getCarMake(); system("pause"); return 0; } void myTitle() { cout << "*************************************************"<<endl; cout << "* Welcome to Michael's *"<<endl; cout << "* Parking Ticket Simulator *"<<endl; cout << "* ============================ *"<<endl; cout << "* *"<<endl; cout << "*************************************************"<<endl<<endl; }

I would create a member variable of the ParkedCar to hold a (or many) ParkingTickets and add a setter which takes a ParkingTicket as an argument.

I created a ParkedCar object within the ParkingTicket class. I've tried using the following code in main to call it, but this doesn't seem to work either. Is my syntax wrong? Or am I doing something else terribly wrong?
Here I have a function in ParkingTicket class to set the car's make from the ParkedCar object.
void setCarMake(string c) { car.setMake(c); }
Now in main, I want the ParkingTicket class (ticket object) to read the ParkedCar object and access the value stored there.
cout << ticket.getCarMake(car.getMake);

As JackOfAllTrades suggests, you can copy the car data to the ticket.ticket.setCar(car); cout << ticket.getCarMake() << endl;
