Vehicle Inheritance

Create a base class Vehicle with member variables std::string make, std::string model, and int year. Create two derived classes: Car and Motorcycle. The Car class should have an additional member variable int door_count, and the Motorcycle class will have a member variable bool has_sidecar to indicate if it has a sidecar. You will then instantiate objects of each derived class and print their details.

Hint

Inherit a struct/class from another with this syntax:

class inherited : public base_class {
};

Answer

#include <iostream>
#include <string>

// Base class Vehicle
class Vehicle {
public:
    std::string make;
    std::string model;
    int year;

    // Method to print vehicle details
    void printDetails() {
        std::cout << "Make: " << make << ", Model: " << model << ", Year: " << year << std::endl;
    }
};

// Derived class Car
class Car : public Vehicle {
public:
    int doors;

    // Method to print car details
    void printCarDetails() {
        // Call the base class method to print common details
        Vehicle::printDetails();
        std::cout << "Doors: " << doors << std::endl;
    }
};

// Derived class Motorcycle
class Motorcycle : public Vehicle {
public:
    bool has_sidecar;

    // Method to print motorcycle details
    void printMotorcycleDetails() {
        // Call the base class method to print common details
        Vehicle::printDetails();
        std::cout << "Has Sidecar: " << (has_sidecar ? "Yes" : "No") << std::endl;
    }
};

int main() {
    // Instantiate a Car object
    Car myCar;
    myCar.make = "Toyota";
    myCar.model = "Camry";
    myCar.year = 2021;
    myCar.doors = 4;

    std::cout << "Car Details:" << std::endl;
    myCar.printCarDetails();

    // Instantiate a Motorcycle object
    Motorcycle myMotorcycle;
    myMotorcycle.make = "Harley-Davidson";
    myMotorcycle.model = "Sportster";
    myMotorcycle.year = 2019;
    myMotorcycle.has_sidecar = true;

    std::cout << "\nMotorcycle Details:" << std::endl;
    myMotorcycle.printMotorcycleDetails();

    return 0;
}
