operator-(std::reverse_iterator)

template< class Iterator > typename reverse_iterator<Iterator>::difference_type operator-( const reverse_iterator<Iterator>& lhs, const reverse_iterator<Iterator>& rhs );		(C++11 前)
template< class Iterator1, class Iterator2 > auto operator-( const reverse_iterator<Iterator1>& lhs, const reverse_iterator<Iterator2>& rhs ) -> decltype(rhs.base() - lhs.base());		(C++11 起) (C++17 前)
template< class Iterator1, class Iterator2 > constexpr auto operator-( const reverse_iterator<Iterator1>& lhs, const reverse_iterator<Iterator2>& rhs ) -> decltype(rhs.base() - lhs.base());		(C++17 起)

返回二个迭代器适配器间的距离。

lhs, rhs

-

要计算距离的迭代器适配器

rhs.base() - lhs.base()
