Merci d'avance.

Bonjour,

le mieux que tu aies à faire, c'est d'utiliser un débogueur. Si ton programme crashe, il t'indiquera immédiatement où. En remontant dans la pile d'appel de fonctions, tu verras ce qui pose problème. Sous Linux, je te conseille Nemiver, et Code::Blocks si tu es sous Windows.

Salut,

J'ai testé ton programme et ça marche.
Un seul problème : le bouton MENU est sans effet.
