数据结构循环队列的实现 在visual c++6.0运行(Circular queue data structure to achieve the visual c++6.0 run)

读取数据，统计所得到的文件中每个字母的权值，创建哈夫曼树，哈夫曼编码。哈夫曼解码，解码后内容写入到指定的文件。 读取数据里面的内容是由英文单词组成。读取文件的时候传入文件存放的路径、读取方式以及读出以后存放的数组，最终可以得到一个存放目标文件内容的数组。 将得到的数组进行字母权值的统计，统计每个字母出现的次数，次数即为每个字母的权值。 将得到的字符数组与权值数组作为创建哈夫曼树的依据，哈夫曼树根据每个字母权值的大小来创建，每个节点，包括权值、父节点、左子、右子和字母本身。 根据哈夫曼树进行编码。形成目标文件的哈夫曼编码，将此编码返回。 根据哈夫曼树得到的数组即为解码数组，解码数组作为解码的结果返回。 写入输出文件，将解码得到的数组、文件的完整路径以及文件的写方式作为参数传入，将数组写入到相应的文件中。 (Read the data, statistical documents obtained weights for each letter, create a Huffman tree, Huffman coding. Huffman decoding, the decoded contents are written to the specified file. Read the content inside is composed of English words. When the incoming file to read the file storage path, read mode and read out after storage array that can eventually get a storage target file contents of the array. The resulting array of letter weights statistics, statistical number of occurrences of each letter, the number is the weight of each letter. The resulting character array with the weights array as the basis for creating Huffman tree, Huffman tree based on the size of the weights of each letter to create, for each node, including weights, parent, left child, right child, and letter itself. According to Huffman coding. The formation of the target file Huffman coding, this code returns. According to Huffman decoding the resulting array is an array, the decoder decodes the result is retur)

C常用算法程序集，一些C语言的基本算法在里面都可以找到。(this is a very good book about c language,you will find it is very useful in your work.)

这个是C++编译的单链表，其中包括多种链表操作，是很好的学习资料。(This is a C++ compiler single linked list, which includes a variety of linked list operations, is a good learning materials.)

数据结构中KMP算法c语言实现，vc6.0环境(KMP algorithm in c language data structure, vc6.0 environment)

说明：  一个用VS2008编写的冒泡排序算法演示程序，数组都是随机生成的。(Bubble Sort)

说明：  离散随机线性系统的卡尔曼滤波。 其中13lman.c是卡尔曼滤波函数，4rinv.c是滤波函数中用到的矩阵求逆函数，13lman0.c是主程序。(discrete stochastic linear Kalman filtering system. 13lman.c which is the Kalman filter function, 4rinv.c filtering function is used in the matrix inversion function, is the main program 13lman0.c.)

根据队列搜索算法的基本思想，现设计了一个简单的结构体数组如下定义代码所示。此结构体数组具备控制结点搜索和存储结点信息和路径的功能，可以较好的实现TDN的最小时间路径搜索。(Search algorithm based on the basic idea of ​ ​ the queue is now designed a simple structure array as defined code. This structure array with the control node and storage node information search and path functions, you can achieve better TDN minimum time path search.)

假设要在足够多的会场里安排一批活动，并希望使用尽可能少的会场。设计一个有效的贪心算法进行安排。（这个问题实际上是著名的图着色问题。若将每一个活动作为图的一个顶点，不相容活动间用边相连。使相邻顶点着有不同颜色的最小着色数，相应于要找的最小会场数。） 对于给定的k 个待安排的活动，编程计算使用最少会场的时间表。 (Suppose you want to arrange a number of activities in the hall more than enough, and want to use as little as possible venue. Design an effective greedy algorithm arrangements. (This problem is actually well-known graph coloring problem. If each activity as a vertex map, with the side connected between incompatible activities. Makes coloring adjacent vertices with minimum number of different colors, corresponding to looking The minimum number of venue.) K to be arranged for a given activity, calculated using a minimum of venue programming schedule.)
