    rder of iteration over a map or a set

    Hi,

    if I iterate over a map or a set, is the order
    specified in which the elements are traversed?

    TIA,

    Schobi

      Yes, the order will be in ascending order of keys.

                  An additional comment to the OP: What "ascending" means in this context
                  depends on the sorting criterion, for which a default value (less) is
                  supplied.

                      Thanks. I think I knew that. I was just
                      wondering whether implementations are
                      required to traverser their trees in
                      this order.
