operator-(std::reverse_iterator) – operator-(std::reverse_iterator)

Synopsis

template <class Iterator>

typename reverse_iterator<Iterator>::difference_type(until C++ 11)

operator-(const reverse_iterator<Iterator> &lhs,

          const reverse_iterator<Iterator> &rhs);

template <class Iterator1, class Iterator2>

auto operator-(const reverse_iterator<Iterator1> &lhs, (since C++ 11)

                                                           const reverse_iterator<Iterator2> &rhs(until C++ 17)

                   ) -> decltype(rhs.base() - lhs.base());

template <class Iterator1, class Iterator2>

constexpr auto operator-(const reverse_iterator<Iterator1> &lhs, (since C++ 17)

                                                                     const reverse_iterator<Iterator2> &rhs

                         ) -> decltype(rhs.base() - lhs.base());

Returns the distance between two iterator adaptors.

Parameters

lhs, rhs – iterator adaptors to compute the difference of

Return value

rhs.base() – lhs.base()
