Inheritance in C++

What is single inheritance in C++?

• In single inheritance, a derived class inherits from multiple base classes.

• In single inheritance, a derived class inherits from only one base class.

• In single inheritance, a derived class inherits from all the classes in the program.

• In single inheritance, a derived class does not inherit from any base class.

Explain the concept of multiple inheritance in C++ with an example.

• A derived class inheriting from two or more base classes

• A class inheriting from its own derived class

• A derived class inheriting from a single base class

• Inheritance of multiple classes from a single base class

What is multilevel inheritance in C++? Provide an example to illustrate this concept.

• Class A -> Class B -> Class C

• Class A -> Class C

• Class A -> Class B -> Class D

• Class A -> Class D -> Class C

Define hierarchical inheritance in C++ and give an example.

• Class A and Class B are sibling classes inheriting from Class C.

• Class A is the parent class, and Class B and Class C are child classes inheriting from Class A.

• Hierarchical inheritance is not supported in C++.

• Class A is the child class, and Class B and Class C are parent classes inheriting from Class A.

Explain the concept of hybrid inheritance in C++ with a suitable example.

• Hybrid inheritance in C++ is when a class is derived from multiple base classes and those base classes are also derived from other classes.

• Hybrid inheritance in C++ is when a class is derived from multiple base classes and those base classes are also derived from the derived class.

• A suitable example of hybrid inheritance in C++ is a class 'A' derived from classes 'B' and 'C', where class 'B' is also derived from class 'D'.

• A suitable example of hybrid inheritance in C++ is a class 'X' derived from classes 'Y' and 'Z', where class 'Y' is also derived from class 'W'.

What are the advantages of using inheritance in C++?

• Simpler code syntax

• Faster execution time

• Code reusability, polymorphism, and hierarchical relationship between classes

• Less memory usage

Discuss the potential drawbacks of using inheritance in C++.

• Tight coupling between classes and the diamond problem

• Increased code reusability

• Enhanced code readability

• Improved code organization

How does C++ support the concept of inheritance?

• Through the use of interfaces

• By using multiple inheritance only

• By creating new classes from scratch

• Through the use of base and derived classes

What are the access specifiers used in inheritance in C++?

• visible, hidden, restricted

• internal, external, local

• unrestricted, confidential, limited

• public, protected, private

Explain the concept of overriding in C++.

• More than one function with the same name in both base class and derived class

• More than one function with the same name in base class only

• More than one function with the same name in derived class only

• Virtual inheritance in C++ is used to create instances of classes that cannot be instantiated directly.
