小编给大家分享一下C++如何实现TCP聊天室功能，相信大部分人都还不怎么了解，因此分享这篇文章给大家参考一下，希望大家阅读完这篇文章后大有收获，下面让我们一起去了解一下吧！
具体内容如下
TCPServer.cpp：
// TCPServer.cpp : Defines the entry point for the console application.#include "stdafx.h"#include<iostream>#include<stdio.h>#include<WinSock2.h>using namespace std;#pragma comment(lib,"ws2_32.lib")const char *WELCOMTOCHATROOM = "欢迎来到聊天室";const char *MESSAGECOMED = "收到客户端发来的信息：";const char *ANSWER = "您的回复是：";const char *WAIFORCLIENT = "等待客户连接.......";int main(){ BOOL bSuccess = FALSE;//是否执行成功 int nError = ERROR; SOCKET socketServ = INVALID_SOCKET; SOCKET socketClient = INVALID_SOCKET; do { WSADATA wsaData; nError = WSAStartup(MAKEWORD(2, 2), &wsaData);//初始化 if (0 != nError) break; //创建Socket socketServ = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); if (INVALID_SOCKET == socketServ) break; //创建地址 sockaddr_in addrServ = { 0 }; addrServ.sin_addr.S_un.S_addr = INADDR_ANY;//所有ip地址 addrServ.sin_family = AF_INET;//ipv4 addrServ.sin_port = htons(10800);//端口 //绑定 if (SOCKET_ERROR == bind(socketServ, (SOCKADDR*)&addrServ, sizeof(addrServ))) break; if (SOCKET_ERROR == listen(socketServ, SOMAXCONN)) break; sockaddr_in addrClient = { 0 }; int nAddrSize = sizeof(addrClient); //等待客户连接 cout << WAIFORCLIENT << endl; socketClient = accept(socketServ, (SOCKADDR*)&addrClient, &nAddrSize); if (INVALID_SOCKET == socketClient) break; if (SOCKET_ERROR == send(socketClient, WELCOMTOCHATROOM, strlen(WELCOMTOCHATROOM)+1,0)) break; char szRecvMessage[MAXBYTE] = { 0 }; char szSendMessage[MAXBYTE] = { 0 }; while (true) { int nResult = recv(socketClient, szRecvMessage, MAXBYTE, 0); if (nResult > 0) { cout << MESSAGECOMED << szRecvMessage << endl; cout << ANSWER; cin >> szSendMessage; if (SOCKET_ERROR == send(socketClient, szSendMessage, strlen(szSendMessage)+1, 0)) break;//跳出while } else if (nResult == 0) { cout << "连接被关闭：" << endl; break; } else { cout << "recv错误！" << endl; break; } } bSuccess = TRUE; } while (false); if (!bSuccess) { nError = WSAGetLastError(); cout << "出现错误信息" << nError << endl; if (INVALID_SOCKET != socketServ) closesocket(socketServ); if (INVALID_SOCKET != socketClient) closesocket(socketClient); } WSACleanup(); system("pause"); return 0;}TCPClient.cpp：
