Forward IteratorA Forward Iterator is an Input Iterator that guarantees a linear traversal over the sequence.
Forward Iterator does not define any new expressions beyond those defined in Input Iterator. However, some of the restrictions described in Input Iterator are relaxed.
| Expression | Expression type |
|---|---|
typename i::next | A model of Forward Iterator |
For any forward iterators i and j the following invariants always hold:
i and j are dereferenceable and i is identical to j, then i::next is identical to j::next.
