RC5 encryption algorithm is a new fast symmetric block cipher developed by Ron Rivest for RSA Laboratories. Intended as a possible successor to the Data Encryption Standard, RC5 has a variable word size, a variable number of rounds, and a variable-length secret key, so the user can explicitly manipulate the trade-off between higher speed and higher security. RC5 is suitable for hardware or software implementations; the encryption and decryption algorithms are exceptionally simple. A novel feature of RC5 is the heavy use of data-dependent rotations.

用C语言编程产生离散单位斜边序列、门序列、指数衰减序列，实现三者卷积，并在显示器上观察到相关序列或卷积的图形。比较经典的卷积C源码-C language programming produce discrete units hypotenuse sequence, the gate sequence, exponential decay sequence, the realization of the three convolution, and observed in the display sequence, or convolution-related graphics.This is the classical convolution C original code

个人感觉是一个不错的学生管理系统,我想对于初学C语言的朋友很有帮助!-Personal feeling is that a good student management system, I would like for the novice C language helpful friend!

一份精美的首页源码。。欢迎下载~很好看的哦-A beautiful home page source code. . Welcome to download the ~ good to see Oh

我比较着急下载资源，这个也是从网上下载的，暂时应急，以后一定将自己写的源码发送上来，是个比较简单的坦克大战，可以学习游戏的简单开发。-download resources, as well as downloaded from the Internet, temporary emergency, I must write their own source of this, was a relatively simple Tankedaizhan. can learn a simple game development.

很多有趣的小程序，对学习C语言有很大的帮助哦 大家一定要-many interesting small program, to learn C language is a great help, oh we must Kankan
