What are abstract functions? Why are they used?
Posted On: Feb 22, 2018
The abstract function or method does not have a body and also it cannot be implemented. The abstract classes cannot be started without the help of the subclasses that help in providing the implementations which are actually for the abstract methods. They actually try developing base classes which help in the custom implementation. The keyword abstract can be used to denote both the abstract methods and also an abstract class.
