Question

求几个小程序的c++代码

学了c++一段时间，想看看一般人家的程序怎么写的，想学着弄一下软件神马的。。。
想看看一些比较简单的软件的程序是怎么样的

感觉上像迅雷美图看看那神马的（不知道复杂不。。）还有一些小程序，如果哪位大大有的麻烦能给我一下么。。具体什么程序不怎么要紧，主要想看看学习学习（最好是实用程序吧，不要专为教学而编的那种）

Answer 1

迅雷那种东西是不会开放源代码的，要找的话可以上开源社区看看，比如http://www.codeproject.com/，上面就有好多有趣的小工具，注释也比较好。

追问

我不是初学者。。谢谢。。。不要拿这些练习给我好么。。。我要的是实用的程序啊。。。

Answer 3

一些SDK包中有sample或demo，其中有实例程序，而且这些程序都很成熟。
比如开源图形库wykobi，比如ObjectARX

Answer 4

去csdn上面下吧，多得很
