实现一个C程序下的词法分析,简单实用,不需要添加任何代码,就可执行,可在DOS或WIN下的各个版本的C程序编辑器下执行-achieve a C program under the lexical analysis, simple and practical, do not need to add any code can be implemented, in DOS or WIN under the various versions of the C program under Executive Editor

这里以开始定义的PASCAL语言子集的源程序作为词法分析程序的输入数据。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。- Here starts the PASCAL language subset source program which defines to take the lexical analyaer the data-in. In the lexical analysis, starts from the article article to scan the source program character, once discovered when conforms to "the word" the definition source program character string, translates it the fixed length the word interior to indicate, and looks up fills in the suitable information table. After the lexical analysis, the source program character string (source program exterior expression) is translated has and so on the long information the word string (source program internal expression), and produces two forms: The chart and the identifier table, they have separately contained in source program all constants and all identifiers.

一个简单的编译源程序-a simple compiler source

java写的PLO词法分析,刚交了作业 没什么大内容,仅供参考-java write lexical analysis of the PLO, has just paid a little big operation, for reference purposes only

该系统是本人课程设计作业，因为时间关系，只用了两天多的时间编成。所以有很多地方没有得到增强。版本为1.0。现作以下升级。 增加NEW，OPEN版本。 提高输入容错。判断输入的对错。 时间关系，搜索功能为线性搜索，现增强如下：f_search:费氏查找法；btree:二叉树查找法；l_search：线性查找法； r_search：递归折半查找法；zcsear:杂凑碰撞查找法；o_sear:插补查找加强法； 排序是冒泡法，现增强为：heaps:累堆排序；binary：二叉树排序；xieer：谢耳排序；sinsert：插入排序；quicks:快速排序；select:选择排序法； 有时间不仿试试。-f_search: Find Act Fernandez btree: binary tree search method l_search: linear search method r_search: Recursive half Find Law zcsear: Find a hash collision law o_sear: interpolation search Enhancement Act sort is bubbling method are enhanced for: heaps: HEAPSORT tired binary: binary tree sort xieer: Xie ears sort sinsert: Insertion Sort quicks: quick sort select: Select Sort Method

c实现的四元式，模拟编译原理来实现，程序本身没什么难度，不过写这种程序能进一步加深对编译原理的理解！-c 4 yuan to achieve the style, analog compiler principles to achieve, the process itself little more difficult, but to write such a procedure would further deepen the understanding of compiler theory!

对pl0语言程序的语法分析源程序，由flex和bison生成。带实验报告。- To the pl0 language procedure grammar analysis source program, produces by flex and bison. Belt test report.
