1、基于TCP的网络聊天程序问题概述：网络聊天是网络应用中的一种常见的功能。TCP是一种可靠的、面向连接、面向数据流的传输协议，多数网络协议都使用TCP协议，包括HTTP和FTP，TCP协议非常适合数据的连续传输。技术难点：TCP通信协议；QTcpsocket的使用。实践方案：在linux_ubuntu下使用qt_eclipse编写c++程序。由面向对象的思想，为了实现程序，在server终端部分有3个类：1.serve2.tcpclient3.tcpserveServe类是继承自QTcpServer,实现TCP协议的服务器；Tcpclient继承自QTcpSocket，实现

2、一个TCP套接字；Tcpserve是一个QDialog,负责服务器终端的对话框显示与控制。如下是对serve的实现代码：Server.h#include#include"tcpclientsocket.h"classServer:publicQTcpServer{Q_OBJECTpublic:Server(QObject*parent=0,intport=0);QListtcpClientSocketList;signals:voidupdateServer(QString,int);publicslots:voi
