Chapter 10: Problem 11

When a class member is declared as protected, what code may access it?

Short Answer

Expert verified

Answer: A class member declared as protected can be accessed by the containing class itself, any class that inherits from the containing class (deriving classes or subclasses), and in C++: classes within the same package.

Step by step solution

Understand Access Specifiers

Access specifiers define the level of access granted to class members (like attributes and methods) in object-oriented programming languages like C++, Java and C#. There are three types of access specifiers: public, private, and protected.

Define 'Protected' Access Specifier

Protected is an access specifier that allows class members to be accessed within the containing class, as well as by classes which inherit from the containing class, but not by other code outside of these two scenarios.

When can Protected Class Members be accessed?

Class members declared as 'protected' can be accessed by: 1. The containing class itself. 2. Any class that inherits from the containing class (deriving classes or subclasses). 3. In C++: Classes within the same package are allowed access to protected class members (this is not applicable to languages like Java and C#). Code outside of these specific scenarios will not be able to directly access protected class members.
