Pointers

_______ members of a base class are never accessible to a derived class.

Private

True/False: A derived class may become a base class, if another class is derived from it.

True

True/False: In C++ 11, if a derived class attempts to override a final member function, the compiler generates an error.

True

True/False: More than one class may be derived from a base class.

True

True/False: Pointers to a base class may be assigned the address of a derived class object.

True

True/False: Static binding occurs when the compiler binds a function call with the function call that resides in the same class as the call itself.

True

True/False: The base class access specification can be viewed as a filter that base class members must pass through when becoming inherited members of a derived class.

True

True/False: When arguments must be passed to the base class constructor, they are passed from the derived class constructor's header line.

True

________ functions are dynamically bound by the compiler.

Virtual
