编译的作业，对词法的分析分类以及发现错误，希望与大家交流，谢谢指教...

VC++编的一个词法分析器-VC series a lexical analyzer

PASCAL语言子集编译器，足够计算机系的学生交作业用了-PASCAL language subset compiler, the enough computer department s students handed over the work to use

大学期间写的一个简单的词法分析器,通过输入符合自定义语法规则的程序,得到分析的二元组-University wrote a simple lexical analyzer through importation from the definition of the rules of grammar procedures, the analysis of binary Group

vb方面的编程，条形码编程。希望对大家有用。-vb aspects of programming, bar code programming.

编制一个词法分析程序，从输入的源程序中，分析出各个具有独立意义的单词，即基本保留字、标识符、常量、运算符、界符五大类。并依次输出每类单词，错误时记下出错的行列，出错原因，然后跳过错误部分继续分析-compiled a lexical analysis procedures from the importation of the source, the analysis of the various independent significance of the word, that is to retain the basic character identifier, constants, and Operators, the industry address five major categories. And each type of output followed by the words, the wrong way down the ranks wrong, wrong reasons, then jump to the wrong part analysis

编译原理课程设计,包括词法分析，语法分析，目标代码优化的编译器,希望大家提出意见-compiler theory of curriculum design, including lexical analysis, grammar analysis, the objectives of optimizing code compiler, we hope that the views

是我刚完成的，大家请多指教- Was I just completes, everybody please advised

现将本人搜集常用的程序设计语言的词法和形式文法提供给大家。其中，词法是按LEX格式编辑，形式文法是按YACC格式书写，大家可直接用LEX和YACC工具编译生成各类程序设计语言的分析器。-commonly used programming language syntax and grammar forms to the public. Among them, morphology is based on LEX format editing, grammar form is written by YACC format, we can use the LEX and YACC tools various compiler generation programming language analyzer.

编译原理实验中的工具FLEX,可以再windows或者DOS下使用-Compilation Principle Experiment tools FLEX, can be used under windows or DOS

LL（1）分析 写的语法分析程序，但是不能实现消除左递归，提取公因子-LL (1) analysis of written grammar analysis program, but can not eliminate the left recursion, extracting common factor
