Thread: how do u access a class protected area?

Code:

int getVar() const
{
     return var;
}

In a very basic sense a class looks like this...

Code:

class A
{
   public: // this is the class interface.

   private: // this is whats encapsulated.

   protected: // This is exactly like private but will be visible in derived classes.
};

This means that there is no difference between private and protected until you inherit from this class then inside the derived class the base class private members are not visible but the base class protected members are visible.
From inside the class you access private and protected members as you do public members but from outside of the class both are inaccessible. Only the interface is visible to the outside world as it should be in any OOP situation.

>i need to know how to access the class protected area.
The whole purpose of protected is to restrict access to anything except the class itself and any derived classes.
