Как я могу вставить в карту с несколькими картами?

Question

Как вставить элемент на следующую карту?

map<Longitud,multimap<Latitud, ID> > posicionGeo; 

Я пытался вставить так:

posicionGeo.insert(make_pair(x.getLongitude(),make_pair(x.getLatitude(),x.getID()))); 

, но это не работает. Выбрасывает эту ошибку:

Похоже, что ваше сообщение в основном кода; добавьте еще несколько деталей. Похоже, что ваш пост - это в основном код; добавьте еще несколько деталей.

Answer 1

я найти решение, вы можете сделать вставку в два этапа:

multimap<Latitud, ID> mymap; 
    mymap.insert(make_pair(x.getLatitude(),x.getID())); 
posicionGeo.insert(make_pair(x.getLongitude(),mymap)); 

, но я не знаю, почему это:

posicionGeo.insert(make_pair(x.getLongitude(),make_pair(x.getLatitude(),x.getID()))); 

не работают, я думаю, что это то же самое.
