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 + ( difference_type n, const basic_const_iterator & i )

requires std:: random_access_iterator < Iter > ;
(2) (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 > is an associated class of the arguments..

Return value

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