Multidimensional mapa s s'utilitzen quan volem assignar un valor a una combinació de tecles. La clau pot ser de qualsevol tipus de dades, incloses les definides per l'usuari. Els mapes multidimensionals són mapes imbricats; és a dir, mapeen una clau amb un altre mapa, que ell mateix emmagatzema combinacions de valors de clau amb els valors assignats corresponents.

Sintaxi:

  Exemple 1:

Now accessing map though iterator

 First key is 0 And second key is 0 And value is 0 First key is 0 And second key is 1 And value is 1 First key is 1 And second key is 0 And value is 1 First key is 1 And second key is 1 And value is 2 Now accessing map though iterator First key is 0 And second key is 0 And value is 0 First key is 0 And second key is 1 And value is 1 First key is 1 And second key is 0 And value is 1 First key is 1 And second key is 1 And value is 2
