给定一个文法，构造词法分析表，实现算符优先词法分析

windowns 环境的lex和yacc编译器工具-windowns environment lex and yacc compiler tool

是关于算术表达式的翻译程序，有词法分析，语法分析，语义分析和三地址码生成-it is a program which is to translate the compute expression.it contains accidence analysis,gramar analysis ,lexeme analysis and three-addr code grenerate.

用Lex和Yacc实现计算器的例程-with Lex and Yacc achieve the routines Calculator

智能的词法分析 ，能任意输入正则表达式，能求出NFA，DFA，minDFA,和最后的匹配情况-Lexical analysis of intelligence, can enter any regular expression can be obtained NFA, DFA, minDFA, and the final match of the situation

用于中文分词的切分词典,还有词性标注,以这个词典数据库为基础建立文本分类,文本检索或文本过滤可以节省很多时间.很全,强烈推荐!-for the Chinese word segmentation Dictionary, and tagging to the dictionary database based text classification, text retrieval or text filtering can save a lot of time. All very strongly recommended!

to maintain address using tree structure

词法分析―分析关键字，运算符，常数并用动态链表保存结果-lexical analysis-keyword analysis, Operators, constant and dynamic results preservation Chain

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.

构造实验一所给文法（应考虑改造）的FIRST集合和FOLLOW集合；构造LL(1)分析表；构造预测分析的总控程序；利用分析表、分析栈和总控程序对源程序进行自上而下的语法分输出整个语法分析过程中栈的变化过程及分析结果，如符合语法规则输出“正确”，否则输出“错误”。 -Experiment to construct a grammar (should consider the transformation) of FIRST and FOLLOW set of the collection construct LL (1) analysis table structural prediction analysis of the master control procedures the use of analytical tables, analyze the stack and the total source code control procedures carried out since the last sub output down syntax parsing process of the whole stack and analysis of the results of the change process, such as the grammatical rules out the " right" , otherwise output " error."
