Simple Dog Class from week 5 DogSimple.cs - source
<csharp>using System;
//Dog simple class definition public class Dog {
public string Name; // the dog's name
public int Age; // the dog's age public int Weight; // the dog's weight public string BarkSound; // the sound of the dog's bark
public Dog() { BarkSound = "Woof!!!"; }
public void Bark() { //put bark code here } public void Eat() { //put eat code here } }</csharp>
Interfaces
Interfaces - implements or derives from
An interface is a class that lacks implementation. The only thing it contains are definitions of events, indexers, methods and/or properties. The reason interfaces only provide definitions is because they are inherited by classes and structs, which must provide an implementation for each interface member defined. Since classes in c# can only be derived from one other class ( in c++ it is possible to derive from many) interfaces are used for multiple inheritance. Like abstract classes you cannot create an instance of an interface on derive from it.
