一个词法分析实验的源代码

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.

此为一编译原理的课程设计大纲，在里面可以根据大纲的要求编写相应的代码-this as a compiler theory of curriculum design outline, the outline can be inside prepared at the request of the corresponding code

《编译原理及实践》一书的电子版，该电子版很清晰- Compiler Construction Principles and Practice of electronic version of the book, the electronic version is very clear

这是编译原理的词法分析源程序- This is translates the principle the lexical analysis source program

编译原理 课程设计报告： 预测分析表的构造- The translation principle curriculum designs reported that, Forecasts the analytical table the structure

这是一个霍夫曼编码解码的源程序,可以用它高效实现霍夫曼解码编码,注释详细,可读性好.压缩包止包括源程序文件,再vc中运行. -This is a source of Hoffman codec, you can use it to achieve efficient coding Huffman decoding, notes in detail, better readability. Compressed packet including the source file only, and then run vc.

this a english paser that is writed in c sharp .net. i hope it will be advatageaus.-this is a english paser that is writed in c sharp .net. i hope it will be advatageaus.

输入已经消除左递归的以及提取公共左因子的LL(1)文法，再输入相应的表达式，若分析成功，则在递归输出过程中输出"acc",若不成功，则有相应的报错以及位置指名。注意，要把同一个非终结符的产生式分成单个输入。他会自动计算first,follow,预测分析表的构造，但并不输出。-importation has been eliminated and left recursive public from the left-LL (1) grammar, further importation of the corresponding expression, if the analysis is successful, the output of the recursive process output "belongs", if successful, there were errors and the corresponding location named. Attention, we should end with a non-escalation of production into a single input. He will be automatically calculated first, follow, and predicting and analyzing the table structure, but does not export.

一个外国人写的词法分析程序，大家可以参考一下，不过代码太多了！ 有点难-a foreigner writing lexical analysis procedures, we can take a look, but too many of code! Hard
