I have been asked this question in final exam.

My question is based upon Defining a New Container in portion Class Hierarchies, Library & Containers of C++

Answer 1

Correct answer is (d) All of the mentioned

Easy explanation - All the STL containers define the iterator types for that container, e.g., iterator and const_iterator, e.g., vector::iterator and the begin/end methods for that container, e.g., begin() and end().
