Interface And Abstract Class In C Example

The member of the interface cannot be static.

Interface and abstract class in c example. Example interface interface animal void animalsound. Interface method does not have a body. All the code needs to be written in the programcs file. An abstract class can have non abstract methodsconcrete methods while in case of interface all the methods has to be abstract.

An abstract class is never intended to be instantiated directly. This is used to denote that the class is an abstract class. In c an abstract class vs interface c has been used for data abstraction. An interface on the other hand can support multiple inheritance which means a class can inherit any number of inheritances.

This class must contain at least one abstract method which is marked by the keyword or modifier abstract in the class definitionthe abstract classes are typically used to define a base class in the class hierarchy. An abstract class can declare or use any variables while an interface is not allowed to do so. Code explanation we first define the abstract class. An interface is better than an abstract class when multiple classes need to implement the interface.

An interface is a completely abstract class which can only contain abstract methods and properties with empty bodies. Step 1 as a first step lets create an abstract class. Interface method does not have a body void run. Note the use of the abstract keyword.

The class will be called tutorial and will just have one method.
