Synopsis
#include <iterator>
template <class BidirectionalIterator,
class T,
class Reference = T&,
class Pointer = T*
class Distance = ptrdiff_t>
class reverse_bidirectional_iterator : public
bidirectional_iterator<T, Distance> ;
template <class RandomAccessIterator,
class T,
class Reference = T&,
class Pointer = T*,
class Distance = ptrdiff_t>
class reverse_iterator : public random_access_iterator<T, Distance>;
Description
The iterators reverse_iterator and reverse_bidirectional_iterator correspond to Random Access Iterators and
Bidirectional Iterators, except they traverse the collection they point to in the opposite direction. The fundamental
relationship between a reverse iterator and its corresponding iterator i is established by the identity:
&*(reverse_iterator(i)) == &*(i-1);
