I am looking for some STL implementation code for this (operator * on
iterator of type T will result in reference to type T (T&)), but can
not find (maybe I search method is not correct). Could anyone post
some internal implementation code please?

Iterators are closely tied to the container for which they were made,
and the implementation can differ greatly depending on the container.

Iterators provide access to the elements of a sequence. Containers are
one way of creating sequences, but not the only way. Unfortunately,
people tend to learn containers first, and give them undue importance,
ending up confused about how the STL works.
