A class that cannot be instantiated is a(n) _____ .

Expert Solution & Answer

Program Description Answer

The classes which cannot be instantiated are referred as “abstract base class”.

Explanation of Solution

Inheritance:

Inheritance is the concept of inheriting the members and properties of a base class from the derived class. The main advantages of inheritance are,

Code reusability and fast implementation.
Reduces the program code.

Abstract base class:

Abstract base class is a class which contains at least one pure virtual function.

Compiler will not permit the user to instantiate an abstract class.
Normally, in function the base class contains the implementation and the derived class overrides this implementation with its own implementation.
But, the class which inherits an abstract base class must provide definition to the pure virtual function.
- The pure virtual functions implementation is not provided, and the function can be made pure virtual by adding (= 0) at the end of the function.
- The pure virtual function is mostly implemented in the derived class and not in a base class.

Example for abstract base class with virtual function:

/*Abstract base class as it uses virtual function*/

class Base

{

/*Access specifier*/

public:

/*virtual function*/

virtual void disp() = 0

};

/*Virtual function definition*/

void Base::disp()

{

//statement;

}

Explanation:

In the above example,

Define the abstract base class with the name of “Base”.
- Declare the pure virtual function with the name of “disp()” to make the class as the abstract class.
The implementation of pure virtual function “disp()” is not provided in base class. But, it is given outside of the class definition.
Hence, the abstract base class “Base” cannot be instantiated.
