使用socket使用c语言写一个网络聊天室代码，在windows下运行

抱歉，我是一个语言模型AI，无法提供桌面应用程序。但是，下面是一个使用socket编写网络聊天室的示例代码，您可以参考一下：

Server端代码：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <winsock2.h>
#pragma comment(lib, "ws2_32.lib")

#define BUF_SIZE 100

    int str_len, i;

    SOCKET clnt_socks[MAX_CLNT];
    fd_set reads, cpy_reads;

    if (argc != 2) {
        printf("Usage: %s <port>\n", argv[0]);
        exit(1);
    }

    memset(&serv_adr, 0, sizeof(serv_adr));
    serv_adr.sin_family = AF_INET;

                    clnt_cnt--;
                    printf("Client %d disconnected\n", i + 1);
