在Windows环境下C语言通过socket客户端向服务端发送整型一维数组并计算和返回结果给客户端，请给出具体代码

客户端代码：

#include <stdio.h>
#include <winsock2.h>

#pragma comment(lib, "ws2_32.lib") //链接ws2_32.lib库

#define BUF_SIZE 1024 //缓冲区大小

int main()
{
    //初始化Winsock库
    WSADATA wsaData;
    if (WSAStartup(MAKEWORD(2, 2), &wsaData) != 0)
    {
        printf("WSAStartup failed!\n");
        return 1;
    }

    //创建套接字
    SOCKET sock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    if (sock == INVALID_SOCKET)
    {
        printf("socket failed!\n");
        WSACleanup();
        return 1;
    }

    //设置服务端地址信息
    SOCKADDR_IN serverAddr;
    serverAddr.sin_family = AF_INET;
    serverAddr.sin_addr.s_addr = inet_addr("127.0.0.1"); //服务端IP地址
    serverAddr.sin_port = htons(12345); //服务端端口号

    //连接服务端
    if (connect(sock, (SOCKADDR*)&serverAddr, sizeof(serverAddr)) == SOCKET_ERROR)
    {
        printf("connect failed!\n");
        closesocket(sock);
        WSACleanup();
        return 1;
    }

    //发送整型一维数组到服务端
    int arr[] = {1, 2, 3, 4, 5};
    int arrSize = sizeof(arr) / sizeof(int);
    char sendBuf[BUF_SIZE];
    int sendLen = sprintf_s(sendBuf, BUF_SIZE, "%d ", arrSize);
    for (int i = 0; i < arrSize; ++i)
    {
        sendLen += sprintf_s(sendBuf + sendLen, BUF_SIZE - sendLen, "%d ", arr[i]);
    }
    send(sock, sendBuf, sendLen, 0);

    //接收服务端返回的结果
    char recvBuf[BUF_SIZE];
    int recvLen = recv(sock, recvBuf, BUF_SIZE, 0);
    if (recvLen > 0)
    {
        recvBuf[recvLen] = '\0';
        int sum = atoi(recvBuf);
        printf("The sum is %d\n", sum);
    }

    //关闭套接字
    closesocket(sock);

    //释放Winsock库
    WSACleanup();

    return 0;
}

服务端代码：

        closesocket(sock);
        WSACleanup();
        return 1;
    }

    //监听客户端连接请求

        closesocket(sock);
        WSACleanup();
        return 1;
    }

            int i = 0;
            while ((p = strtok(NULL, " ")) && i < arrSize)
            {
                arr[i++] = atoi(p);
            }
        }
        int sum = 0;
        for (int i = 0; i < arrSize; ++i)
        {

        }
        char sendBuf[BUF_SIZE];
        sprintf_s(sendBuf, BUF_SIZE, "%d", sum);

    //释放Winsock库
    WSACleanup();
