Необходимо написать программу на архитектуре Клиент-сервер, чтобы с клавиатуры к клиенту вводилось два числа, находилась их сумма (в идеале найти их НОД, но пока бы просто найти сумму) и передавалась серверу.
Вроде как читает два символа, передаёт клиенту, но сумма нормальная не находится, лишь какое-то непонятное число, не могу понять, в чем проблема.
код прикрепляю
Посмотрите пожалуйста, очень надеюсь на вашу помощь
Мейн (клиент?)
