This lecture introduces the concept of multiple inheritance and discusses the issue of ambiguous access in C++. The instructor explains how a subclass can directly access the protected attributes and methods of its superclasses, leading to potential conflicts when attributes or methods share the same name. Various solutions to resolve this ambiguity are presented, including using the scope resolution operator, explicitly indicating the desired method in the subclass, and defining a method in the subclass to clarify the ambiguous invocation. Examples and syntax are provided to illustrate each solution.
