A class that contains a pure virtual function is known as an abstract class. In the above example, the class Shape is an abstract class. We cannot create objects of an abstract class.

WebIn C++, an Abstract Data Type (ADT) is a type that defines a set of operations that can be performed on data without specifying how those operations are implemented. It provides … WebAbstract Data Types in C++. Now that we’ve seen the concept of abstract data types (ADTs), we proceed to examine the mechanisms C++ provides for defining an ADT. Unlike C, C++ allows the data and functions of an ADT to be defined together. It also enables an ADT to prevent access to internal implementation details, as well as to guarantee ...
