Data Abstraction-
In c#, data abstraction is a technique to hide the unwanted or unnecessary data from the user and shows only essential data to the users.
Achieve Data abstraction-
To achieve the data abstraction we used the abstract class with the 'abstract' keyword. We can not create instance of abstract class. To use the method of abstract class which are defined as abstract method are must be override in derived class in which abstract class is inherits. Abstract class is not use directly because it does not allow to create object.
