使用c语言制作局域网五子棋的源代码

以下是使用 C 语言编写的局域网五子棋的源代码示例：

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

#define PORT 8888

int main()
{
    WSADATA wsaData;
    SOCKET serverSocket, clientSocket;
    SOCKADDR_IN serverAddr, clientAddr;
    int iAddrLen = sizeof(clientAddr);
    char recvBuffer[1024], sendBuffer[1024];
    int nRecv, nSend;

    if (WSAStartup(MAKEWORD(2, 2), &wsaData) != 0)
    {
        printf("WSAStartup failed.\n");
        return 1;
    }

    serverSocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    if (serverSocket == INVALID_SOCKET)
    {
        printf("socket failed.\n");
        return 1;
    }

    memset(&serverAddr, 0, sizeof(serverAddr));
    serverAddr.sin_family = AF_INET;
    serverAddr.sin_port = htons(PORT);
    serverAddr.sin_addr.s_addr = htonl(INADDR_ANY);

    if (bind(serverSocket, (SOCKADDR*)&serverAddr, sizeof(serverAddr)) == SOCKET_ERROR)
    {
        printf("bind failed.\n");
        return 1;
    }

    if (listen(serverSocket, 5) == SOCKET_ERROR)
    {
        printf("listen failed.\n");
        return 1;
    }

    printf("Waiting for client...\n");

    clientSocket = accept(serverSocket, (SOCKADDR*)&clientAddr, &iAddrLen);
    if (clientSocket == INVALID_SOCKET)
    {
        printf("accept failed.\n");
        return 1;
    }

    printf("Client connected: %s\n", inet_ntoa(clientAddr.sin_addr));

    while (1)
    {
        nRecv = recv(clientSocket, recvBuffer, sizeof(recvBuffer), 0);
        if (nRecv == SOCKET_ERROR)
        {
            printf("recv failed.\n");
            break;
        }

        recvBuffer[nRecv] = '\0';
        printf("Received: %s\n", recvBuffer);

        // TODO: 处理接收到的数据并发送回复

        if (strcmp(recvBuffer, "quit") == 0)
            break;
    }

    closesocket(clientSocket);
    closesocket(serverSocket);
    WSACleanup();

    return 0;
}

上面的代码是一个简单的服务器程序，它在本地监听指定端口（8888），并等待客户端连接。当客户端连接后，它将等待客户端发送数据，并处理接收到的数据，然后发送回复。

在此示例代码中，需要添加五子棋的游戏逻辑来实现局域网五子棋。具体实现方式因人而异，可以参考其他五子棋游戏的实现方式。
