la difference entre deux std::vector

**mohsenuss91** · 25/03/2015, 09h44

onjour !!! j'utilise BOOST pour un probléme de graphe mining.
le programme complet se trouve ici : http://pastebin.com/8NejJvcx

Je voulais faire une fonction qui a comme arguments deux graphes et qui retourne un vector , ce vector contient la difference entre les aretes des deux graphes.
voila ce que j'ai fais jusqu’à maintenant :

Code :

std::vector<edge_iter> edgesdiff(Graph const& g1,Graph const& g2){
 
std::vector<edge_iter> v1;
std::vector<edge_iter> v2;
std::vector<edge_iter> result;
 
typedef graph_traits<Graph>::edge_iterator edge_iter;
std::pair<edge_iter, edge_iter> ep;
 
edge_iter ei, ei_end;
for (tie(ei, ei_end) = edges(g1); ei != ei_end; ++ei){v1.push_back(ei);}
for (tie(ei, ei_end) = edges(g2); ei != ei_end; ++ei){v2.push_back(ei);}
 
/* d i f f e r e n c e*/
return result;
}

il manque la partie /* d i f f e r e n c e*/ ou je veux faire la difference entre v1 et v2 et l'inserer dans result.
Par difference je veux dire les elements qui sont dans v1 et ne sont pas dans v2 et vice-versa.

Aidez moi a compléter le programme svp!

Quand on a un problème d'algorithme, on regarde ce que propose <algorithm>.

Tu veux la différence entre deux ensembles de valeurs.
Ca tombe bien, il y a ce qu'il faut: set_symmetric_difference.

return result;
}

mais ça me donne des erreurs du type:

C'est toujours la galère de s'y retrouver dans les messages d'erreur du compilateur. Cela étant, il y a toujours ce problème dans ton code que tu mets des itérateurs, pas des valeurs dans les vecteurs.
Or je ne pense pas qu'il soit possible de trier des itérateurs de graphe: en particulier iterator1 < iterator2 ne compile que pour des random_access_iterator

**ternel** · 25/03/2015, 13h48

à moins d'utiliser la seconde forme de la fonction, qui prend un comparateur en argument.
par exemple [](edge_iter const& a, edge_iter const& b) {return *a<*b;}

comment dois je faire pour mettre des valeurs au lieux des littérateurs svp!

**ternel** · 25/03/2015, 14h19

Avec un vecteur de edge, plutot qu'un vecteur de edge_iterator, peut-être?

**stendhal666** · 25/03/2015, 15h39

comment dois je faire pour mettre des valeurs au lieux des littérateurs svp!

Il faut déréférencer un itérateur pour obtenir la valeur sur laquelle il pointe, avec l'opérateur *:

edge_iterator eit = ...
Edge e = *eit;

Donc pour ton programme, comme dit Leternel:

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
std::vector<Edge> model;
//tie(b, e); etc.
std::for_each(b, e, [a](const edge_iterator& it) {model.push_back(*it); });

Eh bien c'est normal, il faut que tu déclares préalablement ei et ei_end:
edge_iterator ei, ei_end;
tie(ei, ei_end) = etc.

**stendhal666** · 26/03/2015, 10h03

std::for_each(ei, ei_end, [a](const edge_iter& it) {model.push_back(*it); });

C'est là qu'est le "a" non déclaré (entre les crochets dans la capture d'environnement: tel que tu l'écris, ça demande au compilateur de capturer par copie un élément 'a' dans le contexte)
Il faut plutôt écrire:

Code :

std::for_each(ei, ei_end, [&](const edge_iter& it) {model.push_back(*it); });

Et normalement, derrière, tu as une liste de fonctions qui aurait pu correspondre.
Sans ca, on ne risque pas de pouvoir t'aider.

Pour lire correctement ce message, je te suggère de le répartir sur plusieurs lignes, et de l'indenter (chaque templatisation étant plus profonde).

**stendhal666** · 26/03/2015, 10h59

je plussoie ce que dit leternel.

Sinon, je me demande où tu définis edge_iter? il faut que le typedef soit dans la fonction template pour qu'il prenne en compte les types en paramètre du template.
