|
Model of Forward Iterator |
Iterator to move relative to |

|
Integer constant |
Number of positions to move |
advance_c<N>(i);
Return type: A model of the same iterator
concept as i.
Semantics: Returns an iterator to the
element N positions from
i. If i
is a Bidirectional
Iterator then N
may be negative.
