friend constexpr basic_const_iterator operator+( const basic_const_iterator& i, difference_type n ) requires std::random_access_iterator <Iter> ;	(1)	(since C++23)

friend constexpr basic_const_iterator operator-( const basic_const_iterator& i, difference_type n ) requires std::random_access_iterator <Iter> ;	(3)	(since C++23)

Returns the iterator i incremented or decremented by n.

1,2) Returns an iterator which is advanced by n positions.

3) Returns an iterator which is advanced by -n positions.

These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when std::basic_const_iterator<Iter>

Return value

1,2) basic_const_iterator(i.base() + n)

3) basic_const_iterator(i.base() - n)
