我在自己的笔记本上练习一些关于TCP聊天软件的视频，但是出现了一些程序崩溃的问题，
我的ip是：
无线局域网适配器 WLAN:

   连接特定的 DNS 后缀 . . . . . . . :
   IPv6 地址 . . . . . . . . . . . . : 2409:8a1e:c91c:39c0:f098:aea1:90ea:f133

程序代码如下：

//服务器端

int main()

        return -4;
    }
    printf("监听成功\n");

    SOCKADDR_IN cAddr = { 0 };
    double len =sizeof cAddr;
    SOCKET clientSocket = accept(serverSocket,(SOCKADDR*)&cAddr,&len );



    if (SOCKET_ERROR == clientSocket)

        closesocket;

        return -5;
    }

    printf("有客户端连接到服务器了:%s\n",inet_ntoa(cAddr.sin_addr));

    char buff[1024];
    while (1)
    {
        r = recv(clientSocket, buff, 1023, NULL);
        if (r>0)
        {
            buff[r] = 0;
            printf(">>%s\n", buff);
        }
    }









    while (1)
    return 0;
}

//客户端

    char buff[1024];

    while (1)
    {
        memset(buff, 0, 1024);
        printf("你想说啥\n");
        scanf_s("%s",&buff);
        send(clientSocket, buff, strlen(buff), NULL);
        
    }
    return 0;
    
}

但在运行后会服务端会在bind环节失败并崩溃:
请求协议成功
创建套接字成功
bind失败

同时弹窗出现debug Error，
program..........\TCP S.exe
Modlue......\TCP S.exe
File:

runtime check failture#0.......

客户端会在连接环节崩溃：
请求协议成功
创建套接字成功

有时也会出现和服务端一样的弹窗，请问要怎么改。

代码我改过了，没有问题，但我的基础设置好象不全，能把这个软件所需要的文件和系统说一下吗
