Increments or decrements the iterator.

Overload  Equivalent to
(let I be it_ .index()
(1) ++ get-iter <I>(); satisfy  <I> ( ) ; return *this;
(2) ++*this;
(3) auto tmp = *this; ++*this; return tmp;
(4) prev  <I> ( ) ; return *this;
(5) auto tmp = *this; --*this; return tmp;
(6)

auto offset = get-iter <I>() - get-begin <I>();
if (n > 0)
advance-fwd <I>(offset, n);
else if (n < 0)
advance-bwd <I>(offset, -n);
return *this;

(7) *this + = -n; return *this;

If it_ .valueless_by_exception() is true

Parameters

n - position relative to current location

Return value

As described above.
