一些简单的C编程实例，初学C者可以参考，应该挺有用。

COBF (aka C-Obfuscator) is a program which manipulates C or C++ sourcefiles in a way that they aren t readable by human beings but they remain compilable. The benefit of COBF lies in the distribution of programs (freeware, shareware, commercial software etc.): The distribution as a executable binary is often too inflexible (especially for Unix or Windows NT, because it is normally not feasible to support all possible platforms) on the other side one might not give away the sourcecode (e. g. it looks poor [badly commented, Spaghetti code], or you just want to prevent plagiarism). Here COBF can play an important role: It removes all comments and sourcecode formattings and renames all variable and function identifiers. See files.txt for a complete list of the files provided with the cobf zip archive! See doc/ for the COBF manual!

一次.net Socket UDP编程 　　最近想写一个网络服务器端的程序，想看看在大量客户端数下程序的运行情况。于是对.net 的Socket编程进行了一些研究，发现.net 3.5 里SocketAsyncEventArgs 是基于IOCP实现。MSDN上有相关的示例，但它是基于TCP协议的，而我想要的是基于UDP协议的。网上很难找到基于UDP协议的SocketAsyncEventArgs示例（UDP需要用IOCP吗？），于是决定自己写一个基于UDP协议的示例，看看它在和大量客户端通讯时的运行情况。 　　程序分为服务器端和客户端，它们使用UDP协议进行通讯。众所周知UDP是无连接的，可我又想计算出有多少客户端和服务器通信，其中又有多少是新的客户端。所以设计让服务器端程序绑定两个端口。一个端口专门用于接收客户端第一次发送过来的数据包；另一个端口负责和已经接入的客户端进行通讯（是不是有点像TCP的接入，例子本身也在模仿Tcp编程）。客户端比较简单让它生成足够多的Socket，然后不断的向服务器端发送数据包即可。
