Tag: Processing abstract class

Abstract classes are used to express broad concepts from which more concrete classes can be derived . An abstract class type object cannot be created. To abstract class types, however, you can use pointers and references.

The abstract keyword is a non-access modifier, used for classes and methods: Abstract class: is a restricted class that cannot be used to create objects (to access it, it must be inherited from another class) . Abstract method: can only be used in an abstract class, and it does not have a body.

The main purpose of abstraction is hiding the unnecessary details from the users . Abstraction is selecting data from a larger pool to show only relevant details of the object to the user. It helps in reducing programming complexity and efforts.

The purpose of an abstract class is to provide an appropriate base class from which other classes can inherit .
