У меня есть клиентская программа в которой вводится массив чисел и сервер в котором вычисляется среднее значение этого массива.
Сервер:

int main()

setlocale(LC_CTYPE, "rus");
WSAData v_2_0;
int WSAStartup_ = WSAStartup(MAKEWORD(2, 0), &v_2_0);
if (WSAStartup_ != 0)
{
cout << "Initialization error" << endl;
}
SOCKET ServerSock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);

sockaddr_in clientAddr = {};
int nAddrLen = sizeof(sockaddr_in);
SOCKET accept_ = accept(ServerSock, (sockaddr*)&clientAddr, &nAddrLen);

if (len <= 0)
{

break;
}
word = (string)buff;

string word_ = word.substr(word.find_first_of(' '), word.find_last_of(' '));

cout << "The sum of numbers =" << sum << endl;

closesocket(ServerSock);

Я хочу, чтоб результат полученный на сервере передался клиенту и там тоже вывелся. Я пробовал обратный метод когда передаешь с клиента на сервер, но результат не передается.
