Comment (by Karalis Apostolos <tolis@…>):

 Thanks for the reply.

 I don't expect unordered map (keys) following a specific order. I thought
 that if i insert into an unordered map (e.g int->int) the pairs 0->5,
 4->3, 6->9, 2->0 and before the insert of the pair 6->9 take the iterator
 of map[4 ] then after the insertion of the last pair, i can print out
 map[4 ], map[6 ] and map[2 ] using the operator ++. This is very useful in
 case of large unordered maps and multithreading (one thread
 inserts/looksup elements and another one checks every x seconds (the next)
 y map's elements, not simultaneously).
