    La bibliothque d'itrateurs dfinit cinq catgories d'itrateurs ainsi qu'une classe d'itrateur "gnrique", des adaptateurs et des fonctions utilitaires.

    Catgories d'itrateurs

    Il existe cinq catgories d'itrateurs: InputIterator, OutputIterator, ForwardIterator, BidirectionalIterator et RandomAccessIterator .

    Au lieu d'tre dfinis par des types spcifiques, chaque catgorie d'itrateur est dfini par les oprations qui peuvent tre effectues sur celui-ci (c'est dire, des concepts). Cette dfinition signifie que n'importe quel type qui prend en charge les oprations ncessaires peut tre utilis comme un itrateur -- par exemple, un pointeur prend en charge toutes les oprations requises par RandomAccessIterator, donc un pointeur peut tre utilis partout o un RandomAccessIterator est attendu.

    Quatre des cinq catgories d'itrateurs peuvent tre organiss en une hirarchie, o les catgories d'itrateurs plus puissants (par exemple RandomAccessIterator) supportent les oprations de catgories moins puissantes (par exemple InputIterator.

    Si un itrateur est dans une de ces catgories et vrifie aussi les qualits requises d'un OutputIterator, alors il est appel un itrateur mutable et supporte la fois entre et sortie. Les itrateurs immuables sont appels itrateurs constants.
