Member access control: private, public and protected
The use of
private
,
public
, and
protected
access control in C++ to members is similar to the access control in other object-oriented languages
The C++ Programming Language
: Page 402, 849
Observations
Access control is applied uniformly to names
Functions
Variables
Types
And others
private/public/protected are NOT used as modifiers of individual members
Access control via private/public/protected can be augmented with use of
friends
Base class access control
Friends
