Salut,

Peux-tu me donner la partie du code concerné car score=(score-(mm[i][2])) n'est pas suffisant pour que je puisse te poser des questions ou te faire modifier quelque chose.

Le programme est gros ? Et le tableau ?

Il faudrait aussi qu'on sache ce qui se passe, si c'est en "complilant" ou à l'exécution etc
