这是一个此法分析器的手工构造实例，程序很简洁。

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

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

oye,不知道哈布，不好就算了，谢谢哈-oye, not knowing Shihab, not even a thank Kazakhstan. .

拿出这个程序来主要是因为原文中只有一个LEX程序,- Puts out this procedure to come mainly is because in the original text only has a LEX procedure,

用 c++写的编译器， 只有语法和词法- Compiler writes which with c, only has the grammar and the morphology

语法分析器 能够对输入的数据进行判断 进行分析 判别输入字符串的各种信息

一个c语言写的词法分析器和语法分析器的简单算法，适用于编译原理的初学者-a written language lexical analyzer and parser simple algorithms, compiler theory applies to the beginners
