Access Specifiers in Inheritance: Understanding Private, Protected, and Public Access
Understanding the impact of access specifiers on inheritance in programming is crucial. In C , you have three main access specifiers: private, protected, and public. Each specifier controls the accessibility of class members to derived classes.
Public Inheritance: What it Means
When you inherit publicly, all public members of the base class become public members of the derived class, and all protected members become protected members. This means the derived class retains the same accessibility levels for those members.
Protected Inheritance: Understanding the Details
Protected inheritance follows similar rules to public inheritance, but with a slight difference. All public and protected members of the base class become protected members of the derived class. This limits accessibility within the derived class and any further derived classes.
Private Inheritance: When Accessibility is Restricted
Private inheritance takes the most restrictive approach. All public and protected members of the base class become private members of the derived class. This means they are only accessible within the derived class itself and not to any further derived classes.
Important Considerations
Choosing Between Access Specifiers:
The choice of access specifier depends on the specific requirements of your design. Here are some guidelines:
