Let inner_ denote the underlying iterator.

1,2) Returns the iterator i incremented by n. Equivalent to: return /*iterator*/(*i.parent_, i.inner_ + n);.

3) Returns the iterator i decremented by n. Equivalent to: return /*iterator*/(*i.parent_, i.inner_ - n);.

4) Calculates the distance between i and j. Equivalent to return i.inner_ - j.inner_;.

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when zip_transform_view::iterator<Const> is an associated class of the arguments.

Parameters

i, j	-	the iterators
n	-	position relative to current location

Return value

1,2) /*iterator*/{ inner_ + n }

3) /*iterator*/{ inner_ - n }

4) i.inner_ - j.inner_
