What I need:

Create an application named TurningDemo that creates instances of four classes: Page, Corner, Pancake, and Leaf.

Create an interface named ITurnable that contains a single method named Turn(). The classes named Page, Corner, Pancake, and Leaf implement ITurnable.

Create each classs Turn() method to display an appropriate message. For example:

• The Pages Turn() method should display You turn a page in a book.
• The Corners Turn() method should display You turn corners to go around the block.
• The Pancake's Turn() method should display You turn a pancake when it's done on one side.
• The Leaf's Turn() method should display A leaf turns colors in the fall.

What I have:

using System; namespace InterfaceDemo { interface ITurnable{ void turn(); } class Page:ITurnable{ public void turn(){ Console.WriteLine("You turn a page in a book"); } } class Conrner:ITurnable{ public void turn(){ Console.WriteLine("You turn corners to go around the block"); } } class PanCake:ITurnable{ public void turn(){ Console.WriteLine("You turn a pancake when it's done on one side"); } } class Leaf:ITurnable{ public void turn(){ Console.WriteLine("A leaf turns colors in the fall."); } } class Program { static void Main() { ITurnable t= new Page(); t.turn(); t= new Conrner(); t.turn(); t=new PanCake(); t.turn(); t=new Leaf(); t.turn(); } }

}

Error I get:
