Access Specifiers in Inheritance in C++

What are access specifiers in C++?

• Modifiers that control the visibility of class members.

• Data types used to define class members.

• Operators used to access class members.

• Keywords that determine the accessibility of class members.

What are the three access specifiers in C++?

• static, const, virtual

• friend, inline, extern

• int, float, double

• public, private, protected

What is the default access specifier in C++?

• friend

• public

• private

• protected

What is the purpose of access specifiers in inheritance?

• To control the visibility and accessibility of class members in the derived class.

• To allow multiple inheritance

• To automatically inherit all class members

• To prevent inheritance from occurring

What is the difference between public and private access specifiers in C++?

• Public access specifier allows access from outside the class, while private access specifier restricts access within the class only.

• Public access specifier restricts access within the class only, while private access specifier allows access from outside the class.

• Public access specifier allows access from within the class, while private access specifier restricts access from outside the class.

• Public access specifier allows access from outside the class, while private access specifier allows access within the class only.

Can a derived class access private members of its base class?

• Yes

• Sometimes

• No

• Only if explicitly allowed

Can a derived class access protected members of its base class?

• Only if explicitly granted access

• Sometimes

• No

• Yes

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

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

• The protected member can be accessed by any class in the program.

• The protected member cannot be accessed by the derived class.

• The protected member can only be accessed by the base class.

• The protected member can be accessed by the derived class.

What is the purpose of using access specifiers in inheritance?

• To automatically inherit all class members

• To control visibility and accessibility of class members in the derived class.

• To allow multiple inheritance

• To prevent inheritance from occurring
