服务器的问题 自己编的

Question

为啥我这个服务器代码老出问题（部分参考博主的代码）

#include "windows.h"
#include "iostream"
#include "process.h"
#include <string>
using namespace std;
#pragma comment(lib, "ws2_32.lib")

void Receive(void* param)
{
    while (1)
    {
        //客户端接受来自服务器的数据
        SOCKET clientSocket = *(SOCKET*)(param);
        char  recvbuf[2048] = {};        //接收缓冲区
        if (recv(clientSocket, recvbuf, 2048, 0) == SOCKET_ERROR)
        {
            cout << "数据接受失败" << endl;
        }
        else
            cout << "【服务器】说:" << recvbuf << endl;
    }
}

void Send(void* param)
{
    while (1)
    {
        //客户端发送数据给服务器
        SOCKET clientSocket = *(SOCKET*)(param);
        char sendbuf[2048] = {};        //发送缓冲区
        cin.getline(sendbuf, 2048);
        if (send(clientSocket, sendbuf, strlen(sendbuf), 0) == SOCKET_ERROR)
        {
            cout << "发送消息失败！";
        }
        else
            cout << "【自己】说：" << sendbuf << endl;
    }
}

int main()
{
    cout << "-----------客户端-----------" << endl;
    WSADATA  wsa;
    if (WSAStartup(MAKEWORD(2, 2), &wsa) != 0)
    {
        cout << "套接字初始化失败!" << endl;
    }
    SOCKET clientSocket;
    if ((clientSocket = socket(AF_INET, SOCK_STREAM, 0)) == SOCKET_ERROR)
    {
        cout << "套接字创建失败!" << endl;
    }
    struct sockaddr_in SeverAddress;        //服务器地址 也就是即将要连接的目标地址
    memset(&SeverAddress, 0, sizeof(sockaddr_in));
    SeverAddress.sin_family = AF_INET;
    SeverAddress.sin_addr.S_un.S_addr = inet_addr("127.0.0.1");  //127.0.0.1表示本机ip地址
    SeverAddress.sin_port = htons(5000);//设定端口号

    //开始连接
    if (connect(clientSocket, (sockaddr*)&SeverAddress, sizeof(SeverAddress)) == SOCKET_ERROR)
    {
        cout << "客户端：和服务器连接失败！" << endl;
        return 0;
    }
    else
        cout << "与服务器连接成功！" << endl;

    //创建两个子线程
    _beginthread(Receive, 0, &clientSocket);
    //_beginthread(Send, 0, &clientSocket);

    Sleep(INFINITE);    //这里采用另外一种技术避免主线程执行完退出——使其无限期休眠
    //    关闭socket
    if (clientSocket != INVALID_SOCKET) {
        closesocket(clientSocket);
        clientSocket = INVALID_SOCKET;
    }

    //    终止
    WSACleanup();
    cout << "客户端退出！" << endl;
    return 0;
}

期待你的回答

你主线程都没退出，发送线程还注释掉了这是想做什么
