Lære Utfordring: Avledede Klasser

En klasse kalt Vehicle er gitt. I tillegg finnes det to andre klasser kalt Car og Plane.

Det er for øyeblikket en feil i koden. For å rette feilen må du la Car og Plane arve fra Vehicle.

Rediger koden slik at Car og Plane blir underklasser av Vehicle.

using System;

public class Vehicle
{
    public int modelYear;
    public float fuel;
}

public class Car
{
    public void Drive()
    {
        Console.WriteLine("The car is now driving.");
    }
}

public class Plane
{
    public void Fly()
    {
        Console.WriteLine("The plane is now flying.");
    }
}

public class Program
{
    public static void Main(string[] args)
    {
        Car c1 = new Car();
        Plane p1 = new Plane();

        c1.modelYear = 2024;
        p1.fuel = 6000;

        Console.WriteLine("Executed Successfully");
    }
}

Bruk symbolet : i syntaksen til en avledet klasse for å angi foreldreklassen.
