Derived Classes PracticeDerived Classes Practice

A class called Vehicle is given. Apart from that there are two other classes called Car and Plane.

There is currently an error in the code. To fix the error you need to make the Car and Plane inherit from Vehicle.

Edit the code such that Car and Plane become the child classes of Vehicle.

cs

index.cs

1. We use the : symbol in the syntax of a derived class to specify the parent class. 

using System;

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

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

public class Plane : Vehicle
{
    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");
    }
}
