You must erase the key and use a different key. A map automatically sorts when you insert elements.

No, that's not possible. An std::map is always sorted by the key type that is given to it at compile-time. The only way you can sort by something else is to copy the contents to a new map or vector which is then sorted on a different key.Quote:

I'm not sure what you mean here.Quote:

Assuming that the OP wants to have the data show up somewhere else in the map, he has to delete the old key and reinsert the data with a new key.Quote:
