tableau dynamique de tableaux statiques.

Bonjour,

J'aimerais faire un tableau (avec vector) de tableau de 3 doubles
Code:

1 2 3 4 5 6 #include <vector> using namespace std; vector<double[3]> vertex; double d[3] = {0.0, 0.0, 0.0}; vertex.push_back(d);
Seulement voila quand je compile le compilateur devient très bavard :

Je n'ai pas trouvé grand chose à propos des tableaux dynamiques de tableaux statiques.
J'aimerais éviter d'utiliser les pointeurs si possible.

Tu ne peux pas stocker un tel tableau directement dans un conteneur. Par contre tu peux utiliser une structure qui contient un tableau.
Code:

1 2 3 4 5 6 7 8 9 struct Tableau { double V[3]; }; Tableau T = {0.f, 0.f, 0.f}; std::vector<Tableau> vertex; vertex.push_back(T);

Il y a un certain nombre de pré-requis pour utiliser un type avec std::vector.
En particulier, il doit être CopyConstructible et Assignable.
Ce n'est pas le cas des tableaux.
