remotelookup.cpp

通过在远端主机上搭建一个远程字典服务服务器

// 我真诚地保证：
// 我自己独立地完成了整个程序从分析、设计到编码的所有工作。
// 如果在上述过程中，我遇到了什么困难而求教于人，那么，我将在程序实习报告中
// 详细地列举我所遇到的问题，以及别人给我的提示。
// 在此，我感谢张老师对我的启发和帮助。下面的报告中，我还会具体地提到
// 他们在各个方法对我的帮助。
// 我的程序里中凡是引用到其他程序或文档之处，
// 例如教材、课堂笔记、网上的源代码以及其他参考书上的代码段,
// 我都已经在程序的注释里很清楚地注明了引用的出处。
// 我从未没抄袭过别人的程序，也没有盗用别人的程序，
// 不管是修改式的抄袭还是原封不动的抄袭。
// 我编写这个程序，从来没有想过要去破坏或妨碍其他计算机系统的正常运转。
// 胡峰令
