用C语言完成适用于Windows系统的一对一的Socket客户端与服务器程序，并满足一下要求： （1）输出每个步骤过程及必要信息，如：监听消息，ip是多少，端口是多少。如出错，则提示具体哪步出错及出错信息 （2）实现客户端的服务器的对话 （3）客户端输入quit后服务器关闭

好的，我了解您的问题。首先，我需要明确一下您的问题，您希望我为您提供一份C语言完成适用于Windows系统的一对一的Socket客户端与服务器程序的代码，这份代码需要满足以下要求：

1. 输出每个步骤过程及必要信息，如：监听消息，ip是多少，端口是多少。如出错，则提示具体哪步出错及出错信息。

2. 实现客户端的服务器的对话。

3. 客户端输入quit后服务器关闭。

是这样吗？

如果是的话，那么我可以为您提供以下的代码实现。请注意，这只是一份示例代码，您需要根据自己的实际情况进行修改和适配。

首先是服务器端的代码：

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

#pragma comment(lib, "ws2_32.lib")

int main()
{
    WSADATA wsaData;
    SOCKET serverSocket, clientSocket;
    struct sockaddr_in serverAddr, clientAddr;
    int clientAddrLen = sizeof(clientAddr);
    char buffer[1024];
    int nret;

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

    // 创建Socket
    serverSocket = socket(AF_INET, SOCK_STREAM, 0);
    if (serverSocket == INVALID_SOCKET)
    {
        printf("Failed to create socket! Error code: %d\n", WSAGetLastError());
        WSACleanup();
        return -1;
    }

    // 绑定Socket
    serverAddr.sin_family = AF_INET;
    serverAddr.sin_port = htons(12345);
    serverAddr.sin_addr.S_un.S_addr = INADDR_ANY;
    if (bind(serverSocket, (struct sockaddr*)&serverAddr, sizeof(serverAddr)) == SOCKET_ERROR)
    {
        printf("Failed to bind socket! Error code: %d\n", WSAGetLastError());
        closesocket(serverSocket);
        WSACleanup();
        return -1;
    }

    // 监听Socket
    if (listen(serverSocket, 1) == SOCKET_ERROR)
    {
        printf("Failed to listen socket! Error code: %d\n", WSAGetLastError());
        closesocket(serverSocket);
        WSACleanup();
        return -1;
    }

    printf("Server is listening on port 12345...\n");

    // 接收客户端连接
    clientSocket = accept(serverSocket, (struct sockaddr*)&clientAddr, &clientAddrLen);
    if (clientSocket == INVALID_SOCKET)
    {
        printf("Failed to accept client! Error code: %d\n", WSAGetLastError());
        closesocket(serverSocket);
        WSACleanup();
        return -1;
    }

    printf("Client connected, IP:%s, Port:%d\n", inet_ntoa(clientAddr.sin_addr), ntohs(clientAddr.sin_port));

    // 循环处理客户端请求
    while (1)
    {
        // 接收客户端消息
        nret = recv(clientSocket, buffer, sizeof(buffer), 0);
        if (nret == SOCKET_ERROR)
        {
            printf("Failed to receive data from client! Error code: %d\n", WSAGetLastError());
            break;
        }
        else if (nret == 0)
        {
            printf("Client closed the connection.\n");
            break;
        }

        printf("Received message: %s\n", buffer);

        // 发送回复消息
        nret = send(clientSocket, buffer, nret, 0);
        if (nret == SOCKET_ERROR)
        {
            printf("Failed to send data to client! Error code: %d\n", WSAGetLastError());
            break;
        }
    }

    // 关闭Socket
    closesocket(clientSocket);
    closesocket(serverSocket);

    // 释放Socket库
    WSACleanup();

    return 0;
}

然后是客户端的代码：

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

#pragma comment(lib, "ws2_32.lib")

int main()
{
    WSADATA wsaData;
    SOCKET clientSocket;
    struct sockaddr_in serverAddr;
    char buffer[1024];
    int nret;

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

    // 创建Socket
    clientSocket = socket(AF_INET, SOCK_STREAM, 0);
    if (clientSocket == INVALID_SOCKET)
    {
        printf("Failed to create socket! Error code: %d\n", WSAGetLastError());
        WSACleanup();
        return -1;
    }

    // 连接服务器
    serverAddr.sin_family = AF_INET;
    serverAddr.sin_port = htons(12345);
    serverAddr.sin_addr.S_un.S_addr = inet_addr("127.0.0.1");
    if (connect(clientSocket, (struct sockaddr*)&serverAddr, sizeof(serverAddr)) == SOCKET_ERROR)
    {
        printf("Failed to connect to server! Error code: %d\n", WSAGetLastError());
        closesocket(clientSocket);
        WSACleanup();
        return -1;
    }

    printf("Connected to server.\n");

    // 循环发送消息
    while (1)
    {
        printf("Please input message (input quit to exit): ");
        fgets(buffer, sizeof(buffer), stdin);

        // 输入quit则退出
        if (strcmp(buffer, "quit\n") == 0)
        {
            break;
        }

        // 发送消息
        nret = send(clientSocket, buffer, strlen(buffer), 0);
        if (nret == SOCKET_ERROR)
        {
            printf("Failed to send data to server! Error code: %d\n", WSAGetLastError());
            break;
        }

        // 接收回复消息
        nret = recv(clientSocket, buffer, sizeof(buffer), 0);
        if (nret == SOCKET_ERROR)
        {
            printf("Failed to receive data from server! Error code: %d\n", WSAGetLastError());
            break;
        }
        else if (nret == 0)
        {
            printf("Server closed the connection.\n");
            break;
        }

        printf("Received message: %s\n", buffer);
    }

    // 关闭Socket
    closesocket(clientSocket);

    // 释放Socket库
    WSACleanup();

    return 0;
}
