Inheritance in C++

What is inheritance in C++?

• Inheritance in C++ is used to create new classes from existing classes

• Inheritance in C++ is a feature that allows a class to access private members of another class

• Inheritance in C++ allows a class to inherit properties and behaviors from another class.

• Inheritance in C++ is a way to override the properties and behaviors of a class

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

• Code reusability, polymorphism, and hierarchical relationship between classes

• Decreased code organization

• Limited code flexibility

• Faster code execution

Parent class is called as

• base class

• derived class

child class is called as

• derived class

• base class

What happens if we try to access a private member of a base class from a derived class?

• It will allow access to the private member

• It will throw a compile-time error

• It will throw a runtime error

• It is not allowed

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.

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 & C

• Class A & B -> Class C

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

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 access specifiers used in inheritance in C++?

• visible, hidden, restricted

• internal, external, local

• unrestricted, confidential, limited

• public, protected, private
