probleme read write serveur/client
bjr,
voila je doi realiser un serveur/client en tcp et pour le moment je voudrai deja essayer que le client enoye la date et l'heure au serveur puis que le serveur l'affiche.
j'utilise les methodes read et write mais le probleme est que le serveur affiche le message en boucle, voici le code:
