c++怎样做客户端和服务端 我用的是microsoft vc ++6.0 步骤
我本来想做一个通信软件,像qq一样,两个人在寝室连接就可以互相通信的那种但是不知如何下手,还请高手指教做的时候要注意哪些,越详细越好如果能让我做出来有追加哦...

给你个最简单的 服务器端客户端程序 是在控制台下面开发
服务器端
// Server.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "winsock2.h"
#pragma comment(lib, "ws2_32.lib")
#include <iostream>
using namespace std;
int _tmain(int argc, char* argv[])
{
const int BUF_SIZE = 64;
WSADATA wsd; //WSADATA变量
SOCKET sServer; //服务器套接字
SOCKET sClient; //客户端套接字
SOCKADDR_IN addrServ;; //服务器地址
char buf[BUF_SIZE]; //接收数据缓冲区
char sendBuf[BUF_SIZE];//返回给客户端得数据
int retVal; //返回值
//初始化套结字动态库
if (WSAStartup(MAKEWORD(2,2), &wsd) != 0)
{
cout << "WSAStartup failed!" << endl;
return 1;
}
//创建套接字
sServer = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if(INVALID_SOCKET == sServer)
{
cout << "socket failed!" << endl;
WSACleanup();//释放套接字资源;
return -1;
}
//服务器套接字地址
addrServ.sin_family = AF_INET;
addrServ.sin_port = htons(4999);
addrServ.sin_addr.s_addr = INADDR_ANY;
//绑定套接字
retVal = bind(sServer, (LPSOCKADDR)&addrServ, sizeof(SOCKADDR_IN));
if(SOCKET_ERROR == retVal)
{
cout << "bind failed!" << endl;
closesocket(sServer); //关闭套接字
WSACleanup(); //释放套接字资源;
return -1;
}
//开始监听
retVal = listen(sServer, 1);
if(SOCKET_ERROR == retVal)
{
cout << "listen failed!" << endl;
closesocket(sServer); //关闭套接字
WSACleanup(); //释放套接字资源;
return -1;
}
//接受客户端请求
sockaddr_in addrClient;
int addrClientlen = sizeof(addrClient);
sClient = accept(sServer,(sockaddr FAR*)&addrClient, &addrClientlen);
if(INVALID_SOCKET == sClient)
{
cout << "accept failed!" << endl;
closesocket(sServer); //关闭套接字
WSACleanup(); //释放套接字资源;
return -1;
}
while(true){
//接收客户端数据
ZeroMemory(buf, BUF_SIZE);
retVal = recv(sClient, buf, BUF_SIZE, 0);
if (SOCKET_ERROR == retVal)
{
cout << "recv failed!" << endl;
closesocket(sServer); //关闭套接字
closesocket(sClient); //关闭套接字

return -1;
}
if(buf[0] == '0')
break;
cout << "客户端发送的数据: " << buf <<endl;
cout << "向客户端发送数据: " ;
cin >> sendBuf;
send(sClient, sendBuf, strlen(sendBuf), 0);

你好
我现在什么都不是很懂,只学了c语言,会用c编一些小程序
我想知道:做一个这样的软件具体步骤是怎样的呀,比如要建立哪些类型的文件,怎样运行什么的
重要的是我在寝室里面两个人就能通信,发消息
先谢谢咯

用过VC6.0没
