W) Iterators

What is a niterator?

Type that can be used to identify and traverse the elements of a container. Container provides iterator. Iterator does not know about container type it originates from.

Iterators can be thought of as an abstraction of pointers.

• Iterators have „star” operator – „*iter” is valid expression
• Iterators have „arrow” operator – „iter->” is valid expression
