In this problem, you need to:

  • Create a new private field called totalCars of type double which tracks the total number of Car objects created;
  • Create a getter method called getTotalCars which simply returns the number of objects;
  • Make sure the value of the totalCars field is incremented every time a new Car object is created.

        this.brandName = brandName;
        this.modelYear = modelYear;
        this.mileage = mileage;

    static void Main()
    {
        Console.WriteLine(Car.getTotalCars());

        Car car1 = new Car("Toyota", 2022, 25.5);
        Car car2 = new Car("Honda", 2020, 30.2);
        Car car3 = new Car("Ford", 2021, 28.8);

        Console.WriteLine(Car.getTotalCars());
    }
}

Oliko kaikki selvää?

Miten voimme parantaa sitä?
