Question

Using the objects you just created, as shown below, call the method to change the access level to the next in the sequence (in C++).

CODE:

#include <iostream>
using namespace std;

class ParkingLot {
private:
bool Paid;
bool Up;
bool Down;

public:
ParkingLot() {
Paid = false;
Up = false;
Down = true;
}

ParkingLot(bool paid, bool up) {
Paid = paid;
Up = up;
Down = !up;
}

void togglePaid() {
Paid = !Paid;
if (Paid) {
Up = true;
Down = false;
} else {
Up = false;
Down = true;
}
}

bool isPaid() {
return Paid;
}

bool isUp() {
return Up;
}

bool isDown() {
return Down;
}
};

int main() {
// create a ParkingLot object using the default constructor
ParkingLot lot1;

// create a ParkingLot object using the overloaded constructor
ParkingLot lot2(true, false);

// display initial state of the barricades for both parking lots
cout << "Parking Lot 1: Paid = " << lot1.isPaid() << ", Up = " << lot1.isUp() << ", Down = " << lot1.isDown() << endl;
cout << "Parking Lot 2: Paid = " << lot2.isPaid() << ", Up = " << lot2.isUp() << ", Down = " << lot2.isDown() << endl;

return 0;
}
