No, They are not obsolete . In fact, there is an obscure but fundamental difference between Abstract Classes/Methods and Interfaces. if the set of classes in which one of these has to be used have a common behaviour that they share (related classes, i mean), then go for Abstract classes/methods.
Read moreWhat is the use of abstract class C++?
The purpose of an abstract class (often referred to as an ABC) is to provide an appropriate base class from which other classes can inherit . Abstract classes cannot be used to instantiate objects and serves only as an interface. Attempting to instantiate an object of an abstract class causes a compilation error.
Read moreWhat is the purpose of an abstract class?
The purpose of an abstract class is to provide a blueprint for derived classes and set some rules what the derived classes must implement when they inherit an abstract class . We can use an abstract class as a base class and all derived classes must implement abstract definitions.
Read moreWhat is an abstract class in C ++? Why it is required?
By definition, an abstract class in C++ is a class that has at least one pure virtual function (i.e., a function that has no definition). The classes inheriting the abstract class must provide a definition for the pure virtual function; otherwise, the subclass would become an abstract class itself.
Read moreWhat is an abstract class explain with an example?
Abstract classes are essential to providing an abstraction to the code to make it reusable and extendable. For example, a Vehicle parent class with Truck and Motorbike inheriting from it is an abstraction that easily allows more vehicles to be added .

Parent class is the class being inherited from, also called base class. Child class is the class that inherits from another class, also called derived class .
