code:

Penguin penny = new Penguin();
penny.Fly();
class Vertebrate
{
        public int Legs { get; set; }
}

class Bird : Vertebrate
{
    public double Wingspan;
    public void Fly()
    {
        //code to make ti fly
        Console.WriteLine("I'm flying!");
    }
}

class Penguin : Bird
{
    public void Fly()
    {
        Console.WriteLine("Penguins can't fly!");
    }
}

Output: Penguins can't fly!
