Module: Standard C++ Library Library: Iterators
Header
The header <iterator> represents the Iterators library of the Standard C++ Library. It defines:
the class template iterator_traits and two partial specializations of iterator_traits on pointers and const pointers
the classes input_iterator_tag, output_iterator_tag, forward_iterator_tag, bidirectional_iterator_tag and random_access_iterator_tag
the class templates reverse_iterator, back_insert_iterator, front_insert_iterator, insert_iterator, istream_iterator, ostream_isterator, istreambuf_iterator, and ostreambuf_iterator
the helper function templates advance(), distance(), back_inserter(), front_inserter(), inserter()
a set of relational operators that C++ programs may use to perform equality and inequality tests on specializations of reverse_iterator
the equality and inequality operators specialized for istream_iterator and istreambuf_iterator
