24 Iterators library [iterators]

24.5 Iterator adaptors [predef.iterators]

24.5.1 Reverse iterators [reverse.iterators]

24.5.1.3 reverse_iterator operations [reverse.iter.ops]

24.5.1.3.1 reverse_iterator constructor [reverse.iter.cons]

reverse_iterator();

Effects: Value initializes current. Iterator operations applied to the resulting iterator have defined behavior if and only if the corresponding operations are defined on a value-initialized iterator of type Iterator.

explicit reverse_iterator(Iterator x);

Effects: Initializes current with x.

template <class U> reverse_iterator(const reverse_iterator<U> &u);

Effects: Initializes current with u.current.
