const

Provides an arbitrary access to the underlying iterated sequence.

Parameters

n	A signed integral offset of a position of the element of interest with respect to the position of the current iterator.

Returns

A result of transformation of a result of dereferencing of the corresponding base iterator at a position offset by n.

The operator is only implemented by random-access transforming iterators, i.e. if the adopted iterator implements the random-access semantics.
