The class in c++ which act only as a base class and object of it cannot be created is

Answer 1

Answer:

abstract class

Explanation:

Abstract classes (C++ only):-- 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. ... A class derived from an abstract base class will also be abstract unless you override each pure virtual function in the derived class.

Answer 2

The class in C++ which act only as a base class and object of it cannot be created is Abstract class.

• A class that is specifically intended to be used as a base class is known as an abstract class. There is at least one pure virtual function in an abstract class.
• In the declaration of a virtual member function in the class declaration, you declare a pure virtual function by using the pure specifier (= 0).
• Functions with virtual members can be inherited. Unless you override each pure virtual function in the derived class, an abstract base class will also be an abstract class.
• A class that is abstract serves as a suitable base class from which other classes can inherit.
• Abstract classes only act as interfaces and cannot be used to create new objects. A compilation error results from attempting to instantiate an object of an abstract class.
