Can protected members be accessed by objects C++?

You can only access protected members in instances of your type (or derived from your type). You cannot access protected members of an instance of a parent or cousin type. In your case, the Derived class can only access the b member of a Derived instance, not of a different Base instance.

Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).
