操作系統(tǒng)實驗網(wǎng)絡通信

1、一、實驗題目實驗WinSock 網(wǎng)絡通信二、實驗要求通過Win Sock編程實現(xiàn)網(wǎng)絡通信。具體形式為面向連接的TCP 客戶機 - 服務器模式；在兩臺機器(在一臺機器上也可)上一次啟 動服務器、客戶端；在客戶端輸入正確的服務器地址后確認連接 是否成功，若成功則可以在客戶端和服務器之間實現(xiàn)互相收發(fā)數(shù) 據(jù)，并且都可以用特定字符串控制退出三、實驗環(huán)境( 1) 使用的操作系統(tǒng)及版本。Windows xp professional( 2) 使用的編譯系統(tǒng)及版本。Visual c+ 6.0五、實驗源代碼 服務器端程序 server.cpp#include <iostream.h>#include
