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.

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

按照清华大学的教材，自己用C++做的一个小的哈夫曼编码器-materials they used to do a C minor Huffman encoder

用java编译的PL0编译器 附带解释器-java compiler with the PL0 compiler fringe Interpreter

用C++编写的一个简单C语言词法分析器，把需要分析的内容保存在C:input.txt，分 析完毕好保存在C:output.txt-Using C++ to prepare a simple C language lexical analyzer, the need to analyze the contents stored in C: input.txt, finished the analysis of well preserved in the C: output.txt

GNU的词法/语法分析器bison源码，最新版本bison-2.1-GNU/parser bison source, the latest version of bison- 2.1

C++ C 词法分析器，编译原理， 运行时输入文件（input.txt）路径，文件内容为{}BEGIN FOR(I=0 I

简单的词法分析，可以识别关键字错误，识别无效符号等等，通用！-Simple lexical analysis to identify the wrong keywords, identify invalid symbols and so on, General!

这个是我编译原理课程设计的 内容，呵呵 我遍的是词法分析，基本的功能都能够实现，如词法分析，词法查错，删除无实质意义的字符等，不懂编译的就不用看了，编译真的很难！！！不过好象没什么用-this my compiler theory of curriculum design, Oh my times of lexical analysis, the basic functions are to achieve, such as lexical analysis, lexical troubleshoot, remove no real significance of the characters, do not know the compiler would not have to read, compile it really hard! ! ! But it seems usele

C++编写的C++词法分析器，比较全-C compilation C morphology analyzer, compared with entire
