Description: 操作系统中的文件是通过文件目录项来管理的，为了管理和查找的方便，按层次把文件目录项组织起来，同一层上的目录构成该层上的目录，第一层为根目录，一下为各层子目录。 假设以一串字符代表一个文件，每个字符表示一个记录。 在建立上述目录结构的基础上，建立相应的管理系统并要求完成以下各项操作： 1． 一次建立各个文件 2． 查访两个用户的所有文件 3． 查访用户sun 是否有文件AB 4． 删除用户sun的文件AC,然后在分别查访两个用户的全部文件，检查是否已经删除文件AC 5． 撤销用户sun,并检查是否被删除 6． 删除用户sun的全部文件，然后在撤销sun用户，在查访用户sun, 检查其是否已被撤销。 在建立一个新用户及新用户的两个文件，然后查该两个用户的所有文件-operating system, the paper is to document catalog items to the management, in order to manage and facilitate the search, according to the document level directory entries organizations, the same floor on which constitute the directory contents on the floor, the first layer of the root directory to look for levels of subdirectories. Assuming that the representative of a string of characters, each character expressed a record. In establishing the directory structure on the basis of the establishment of a corresponding system of management and asked to accomplish the following : 1. Once established two separate files. Visits to the two users of all three documents. Sun user visits whether documents AB 4. Sun users to delete the documents AC, then two separate visits to all users of the docum

Description: 该词法分析程序用VC++ 6.0编写，以FileOpenDialog打开的*.c或*.cpp文件为语言字集的源程序作为词法分析程序的输入数据,经词法分析程序分析后的结果保存在源文件的同目录的output.txt文件中。在词法分析中，自文件头开始扫描源程序字符，一旦发现符合“单词”定义的源程序字符串时，将它翻译成固定长度的单词内部表示，并查填适当的信息表。经过词法分析后，源程序字符串（源程序的外部表示）被翻译成具有等长信息的单词串（源程序的内部表示），并产生两个表格：常数表和标识符表，它们分别包含了源程序中的所有常数和所有标识符。-the lexical analysis procedures used to prepare VC 6.0 to FileOpenDialog open *. c *. cpp documents or language character sets for the source as lexical analysis of the data entry process, the analysis of lexical analysis procedures after the results stored in the same source file directory paper output.txt .

Description: 从空格(ASCII码32)到~(ASCII码126)。表内的第一行与表头相同，下面的每一行都与上一行的内容相同，只是字符相左移动了一个位置。这样，下一行的最后一个字符与上一行的第一个字符相同。
为了进行文本编码，可以任意选择一个字符串，称之为编码字符串，也就是常说的密钥。为解释编码方法，我们假设密钥是Walrus，待编码的文本（即常说的明文）是：
Meet me in St. Louis
我们在待编码的文本之上重复书写上述密钥，使得其长度与待编码文本相同：
WalrusWalrusWalrusWa
Meet me in St. Louis
从上述两行文本中按列对应方式依次提取一个字符，可得到多个字符对：WM、ae、le等，这些字符对可用作上表的索引。这样，依次以这些字符对作为索引可从上表查到一系列字符，这些字符就构成了文本编码，即常说的密文。例如，第W行第M列队应得字符是%，因此编码的第一个字符就是%；第a行第e列对应的字符是G；第l行第e列对应的是R。依次进行上述查找操作，可以得到完整的密文
%Grgua=aVauGLol?eiAU
进行相反的操作就可对该文本解码。
编写编码/解码程序，可以对文本文件或键盘输入的字符串进行编码/解码，在选择编码解码后，需要提示用户输入密钥。

Character movement is a curator position. So, the next line of characters with a final party on the first character of the same. To text encoding, can choose an arbitrary string, the string as coding, which is often said that the key. To explain the encoding method, we assume that key is Walrus when coding the text (often said that an express) : Meet me in St..

Description: 一：问题描述
针对某个集体（比如你所在的班级）中的“人名”设计一个哈希表，使得平均查找长度不超过R，完成相对的建表和查表程序。
二：基本要求
假设人名为中国人姓名的汉语拼音形式。待填入哈希表的人名共有30个，取平均查找长度的上限为2。哈希函数用除留余数法构造，用伪随机探测再散列法处理冲突。
三：实现提示
如果随机函数自行构造，则应首先调整好随机函数，使其分布均匀。人名的长度均不超过19个字符（最长的人名如：庄双双（ZHAGN SHUANG SHUANG）。字符的取码方法可直接利用C语言中的tosacii函数，并可对过长的人名先作折叠处理。
四：需求分析
本演示程序是对哈希表的建立和查找进行演示，主要数据来自自己编写的人名“A~~Z”等字母组成，拼音由开头的字母组成的词组，查找时用伪随机探测再散列法处理冲突。随机产生人名的位置。具体的程序内容在源程序里面有比较详细的解析。程序的运行在下列有详细的介绍。
-one : Problem description against any collective (such as your own classes) of "names" design a hash table. you make the average length of not more than R, completes the construction and Lookup Table procedures. Two : the assumption that the basic requirements were known as the Chinese name of Chinese pinyin form. Hash Table question Enter the names of a total of 30, you take the average length of a maximum of two. Hash functions with a few exception I stay constructed using pseudo-random re-hash detection method to resolve disputes. 3 : Achieving suggested random function on its own if the structure should first be adjusted his random function, it evenly distributed. Names not on the length of more than 19 characters (the longest names such as : both Chong (ZHAGN SHUANG SHUANG).

Description: 移植到MCS51的uCOS_II。
1。在文件OS_CORE.C中OSMapTbl和OSUnMapTbl数组用于查表，所以应该放在code里。
增加code关键字。UCOS_II.H和OS_CORE.C。
2。OS_CFG.H堆栈大小MaxStkSize改为900。
3。OS_CPU_C.C的InitTimer0函数增加了关于开T0中断的解释。
允许T0中断，此时EA=0(51上电缺省值)，中断还不会发生，满足在OSStart()前不产生中断的要求。
4。修改中断处理流程，以便严密监视中断嵌套情况。每个中断进入后立即进行OSIntNesting+1原语操作。
5。增加printf函数的移植，支持灵活的数据显示。支持标准或长二进制/八进制/十进制/十六进制/无符号整数，
支持字符、字符串、浮点数、百分号％。其中，浮点数在整个范围内被完全支持，统一采用科学记数法显示。
