10.4. Revisiting Iterators

In addition to the iterators that are defined for each of the containers, the library defines several additional kinds of iterators in the iterator header. These iterators include

• Insert iterators: These iterators are bound to a container and can be used to insert elements into the container.

• Stream iterators: These iterators are bound to input or output streams and can be used to iterate through the associated IO stream.

• Reverse iterators: These iterators move backward, rather than forward. The library containers, other than forward_list, have reverse iterators.

• Move iterators: These special-purpose iterators move rather than copy their elements. We’ll cover move iterators in § 13.6.2 (p. 543).
