An Abstract method is a method without a body . The implementation of an abstract method is done by a derived class. When the derived class inherits the abstract method from the abstract class, it must override the abstract method. This requirment is enforced at compile time and is also called dynamic polymorphism.14 Mar 2019

An Abstract Data Type is a special data type that is defined by a set of values and a set of operations on that type . We call these data types as “abstract” because these are independent of any implementation.
Read moreWhat is abstract data type in data structure?
An ADT is a mathematical model of a data structure that specifies the type of data stored, the operations supported on them, and the types of parameters of the operations . An ADT specifies what each operation does, but not how it does it. Typically, an ADT can be implemented using one of many different data structures.

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

Edpresso Team. 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 abstract class in C programming?
An abstract class is a class that is designed to be specifically used as a base class . An abstract class contains at least one pure virtual function. You declare a pure virtual function by using a pure specifier ( = 0 ) in the declaration of a virtual member function in the class declaration.

Abstract Data Type(ADT) is a data type, where only behavior is defined but not implementation. Opposite of ADT is Concrete Data Type (CDT), where it contains an implementation of ADT. Examples: Array, List, Map, Queue, Set, Stack, Table, Tree, and Vector are ADTs.
