风靡ios,Android世界的Flappy Bird的C语言版，附带exe文件。这是一款很好玩很有意思的游戏，但难度很大。我根据互联网上的版本修改，去除了界面上的一些文字，让整体更加简洁。如果有初学者想要学习用C语言写游戏，这是一个比较好的小例子。

应用背景JPHide 和JPSeek 的源代码！JPHide&JPSeek是一个JPEG图像的信息隐藏软件！-JPHide and JPSeek source code! JPHide & JPSeek is a JPEG image information hidden software!关键技术JPHIDE and JPSEEK are programs which allow you to hide a file in a jpeg visual image. There are lots of versions of similar programs available on the internet but JPHIDE and JPSEEK are rather special. The design objective was not simply to hide a file but rather to do this in such a way that it is impossible to prove that the host file contains a hidden file. Given a typical visual image, a low insertion rate (under 5%) and the absence of the original file, it is not possible to conclude with any worthwhile certainty that the host file contains inserted data. As the insertion percentage increases the statistical nature of the jpeg coefficients differs from "normal" to the extent that it raises suspicion. Above 15% the e

在稀疏矩阵相乘的算法当中，关键是通过给定的行号i和列号j找出原矩阵的对应元素值，这里设计了一个函数value，当在三元组表示中找到时返回其元素值，找不到时说明该位置处的元素值为0，因此返回0。然后利用该函数进行矩阵相乘，若求出某个元素值不为0，则将其存入结果矩阵的三元组表示中，否则不存入。
