这是2013编程之美比赛的第一题，传话游戏，感兴趣的朋友可以下载过去看看。(This is the first title of the 2013 Beauty of Programming Competition, messenger games, interested friends can download to look at the past.)

对一个含有多次谐波的信号作FFT变换，利用相关分析法提取它的工频信号。(For a signal containing multiple harmonics for FFT transform using correlation analysis to extract its frequency signal.)

程序所能达到的基本可能：通过随机数据产生N个随机数，作为输入数据作比较；对常用的内部排序算法：直接插入排序、简单选择排序、冒泡排序、快速排序、希尔排序、归并排序进行比较：比较的指标为关键字参加的比较次数和关键字的移动次数（关键字交换记为3次移动）。最后结果输出各种排序算法的关键字参加的比较次数和关键字的移动次数，并按从小到大排列。

排序系统设计 功能：设编号为1，2，3，……，n的n(n>0)个人按顺时针方向围坐一圈，每个人持有一个正整数密码。开始时任选一个正整数做为报数上限m，从第一个人开始顺时针方向自1起顺序报数，报到m是停止报数，报m的人出列，将他的密码作为新的m值，从他的下一个人开始重新从1报数。如此下去，直到所有人全部出列为止。令n最大值取30。要求设计一个程序模拟此过程，求出出列编号序列。 -Sorting system design features: Let numbered 1,2,3, ... ..., n of the n (n> 0) individuals sitting clockwise circle, each person holds a positive integer password. The beginning of a positive integer as reported optional maximum number of m, starting from the first person in a clockwise direction starting from a sequence reported the number of m is to stop the newspaper to report the number of people who reported m out of the column, his password as a new m value, the next person start from his re-reported from a number of. If things go on, until all of the column until all the up. Make n take the maximum 30. To design a program to simulate this process, find out the column number sequence.

进行结构响应分析的Wilson法，是直接积分的基本算法之一，相信进行有限元动力分析编程的诸位都能用上(structural response analysis of Wilson, which is direct integration one of the basic algorithm, believe that the dynamic finite element analysis program you can use)

VC++实现类似于QQ文件传输功能的文件发送与接收程序示例，分为服务端和客户端，客户端首次接收数据，将判断文件包大小，数据包中一定包含完整的数据包结构信息，数据不一定完整；读取数据包的大小，包含数据包结构大小和数据大小，之前接收的数据与现在接收的数据能够构成至少一个完整的数据包，文件接收完毕则设置结束标记，若终止的连接，则弹出窗口告诉用户，对方终止了文件传送。 　　服务端程序是比较简单的，基本是复制文件数据、判断文件是否传递成功、等待对方收受发送任务或取消发送任务，分包继续发送文件等功能(VC++ implementation is similar to QQ file transfer capabilities to send and receive files program examples, divided into server and client, the client receives the first data packet to determine the file size, the packet must contain the complete information packet structure, the data is not must complete reading packet size, including the size and structure of the data packet size, and previously received data received data can now constitute at least one complete packet, the file has been received then set the mark, if the connection is terminated, the pop-up window telling the user, the other party to terminate the file transfer. Server program is relatively simple, basically copying the file data, to determine whether the file transfer is successful, waiting for the other to accept or cancel the sending task sends tasks, subcontractors continue to send files and other functions )
