Increments or decrements the iterator.
Let current_, end_, stride_, and missing_ be the data members of the iterator.
auto r = i; r += n; return r;.auto r = i; r -= n; return r;.N be x.current_ - y.current_. Returns: (N + x.missing_ - y.missing_) / x.stride_, if Base models forward_range. -/*div-ceil*/(-N, x.stride_), if N < 0. /*div-ceil*/(N, x.stride_) otherwise.return /*div-ceil*/(x.end_ - x.current_, x.stride_);.return -(s - x);.These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when stride_view::iterator<Const> is an associated class of the arguments.
| x, y, i | - | the iterators |
| s | - | a sentinel |
