j'aime b1 ay niveau du void modification lorsque j'appui sur confirmer les données seront modifiée dans le fichier text et au niveau du void suppression lorsque j'appui sur supprimer le code la tailee et le poids seront supprimées de la fichier text fpersonne.txt
et meeerccciii

Merci de montrer ce que tu as fait et de nousvdire là où tu bloques on pourra t'aider plus facilement.
