operator- template<typename I , typename F > template<bool _ = true> difference_type operator- ( const transform_iterator< I, F > & lhs, const transform_iterator< I, F > & rhs ) friend Computes the difference between two iterators. Parameters lhs,rhs The iterators to compare. Returns The result of lhs.base() - rhs.base().
