1. 實現**
2. 聊天室服務端：tcp_server_chat.cpp
#include // winsock2的標頭檔案
#include
#pragma comment(lib, "ws2_32.lib")
using namespace std;
// stdcall的執行緒處理函式
dword winapi threadfun(lpvoid lpthreadparameter);
int main()
// 1. 建立流式套接字
socket s = socket(af_inet, sock_stream, ipproto_tcp);
if(s == invalid_socket)
// 2. 繫結埠和ip
sockaddr_in addr;
memset(&addr, 0, sizeof(sockaddr_in));

addr.sin_addr.s_addr = inet_addr("127.0.0.1");
int len = sizeof(sockaddr_in);
if(bind(s, (sockaddr*)&addr, len) == socket_error)
// 3. 監聽
listen(s,5);
// 主線程迴圈接收客戶端的連線
while(true) }
// 6.關閉監聽套接字
closesocket(s);
// 清理winsock2的環境
wsacleanup();
return 0;
}dword winapi threadfun(lpvoid lpthreadparameter)
; sprintf(buf,"歡迎 %d 進入聊天室！",c);
send(c,buf, 100, 0);
// 迴圈接收客戶端資料
int ret=0;

cout << c << " 說：" << buf2 << endl;
} while (ret!=socket_error && ret!=0);
cout << c << "離開了聊天室！";
return 0;
}啟動聊天室服務端：
3. 聊天室客戶端：tcp_client_chat.cpp
#include//winsock2的標頭檔案
#include
usievnyeyng namespace std;
//勿忘，鏈結dll的lib
#pragma comment(lib, "ws2_32.lib")
int main()
//1.建立流式套接字
socket s = socket(af_inet, sock_stream, ipproto_tcp);
if (s == invalid_socket)
//2.鏈結伺服器
sockaddr_in addr;
addr.sin_family = af_inet;
addr.sin_port = htons(8000);
addr.sin_addr.s_addr = inet_addr("127.0.0.1");
int len = sizeof(sockaddr_in);
if (connect(s, (sockaddr*)&addr, len) == socket_error)
//3接收服務端的訊息
char buf[100] = ;
recv(s, buf, 100, 0);
cout << buf << endl;
//3隨時給服務端發訊息
int ret = 0;
do ;
cout << "請輸入聊天內容:";
cin >> buf;
ret = send(s, buf, 100, 0);
www.cppcns.com } while (ret != socket_error&& ret != 0);
//4.關閉監聽套接字
closesocket(s);
//清理winsock2的環境
wsacleanup();
return 0;
}啟動2個客戶端
