Public, Private and Protected Inheritance in C++:
When deriving a class from a base class, the base class may be inherited through public, protected or private inheritance. The type of inheritance is specified by the access-specifier as explained above.
We hardly use protected or private inheritance, but public inheritance is commonly used. While using different type of inheritance,
following rules are applied −
Public Inheritance − When deriving a class from a public base class,public members of the base class become public members of the derived class and protected members of the base class becomeprotected members of the derived class. A base class's privatemembers are never accessible directly from a derived class, but can be accessed through calls to the public and protected members of the base class.
Protected Inheritance − When deriving from a protected base class, public and protected members of the base class become protectedmembers of the derived class.
Private Inheritance − When deriving from a private base class, public and protected members of the base class become privatemembers of the derived class.
