通过设计编制调试一个具体的词法分析程序，加深对词法分析原理的理解。并掌握在对程序设计语言源程序进行扫描过程中将其分解为各类单词的词法分析方法。...

本程序不能编译除大小写字母之外的编码 本程序需事先建立字母权值文后件才可运行 本程序从文件中读入文字，编译后写入文件，所以屏幕上不会直接出现答案-not build this program in addition to case-insensitive outside of the coding process required prior to the establishment of the letters after the value of the text pieces can Win OK this program read from the file into the text, compiled into the paper, not directly on the screen appeared the answer

ldpc译码器 目前通信系统中很多标准都在采用ldpc码，所以他很重要-LDPC decoder, many of the current communication system standards in the use of LDPC code, so he is very important

LL(1)的语法分析器，VC6.0编译器通过，输入输出的文件名详见代码，输出文件中的分析过程和编译原理课本要求类似，根据不同的句子可能需要重新调整对齐格式-A LL(1) parser, built by MS VC 6.0, an assignment of my Complier Principles course

vc实现的pl0编译器,有读取输出功能-read() -write(),这个源码对初学编译原理者有很好的指导作用,我当初学的时候用了3天看懂了源码,也对编译原理更加理解了,毕竟只学理论不看代码是不可能真正理解的,原作者是dwing,我对代码做了一些修改,在此感谢dwing提供的代码-vc achieve pl0 compiler, a reader output- read ()- write (), the source for beginners compiler principles are very good role in guiding, I had time to study the use of three days to read the source code, but also to build a greater understanding of the tenets of all, the theory is not see the code is impossible to truly understand the original author dwing yes, I made some code changes like to thank the code dwing
