十分详细的编译原理课件，来自北京大学，请大家评鉴。

delphi实现的sql解析器，可以对各种sql语句进行解析，产生语法树。-realize the sql parser delphi can parse the various sql statements, resulting in tree grammar.

是关于一个词法分析器的一个程序-Is about a morphology analyzer procedure

一个简单的C语言编译器-a simple C language compiler

这是一个很不错的词法语法分析器! 很适合计算机专业的大学生学习参考-This a very good syntax analyzer! Computer is very suitable for professional students studying reference

PKU_1205 水处理厂输送水的问题，考虑沿岸城市(水处理厂)的数量，程序能确定输送方式的种数-PKU_1205

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

一个词法分析器程序- A morphology analyzer procedure

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.

词法分析器：源程序的运行方式： 运行程序 输入一个已存在的文本文档的文件名。如：input.txt 如果要对整个程序进行语法分析，则按‘y’键，否则按‘n’键 如果要对程序进行语法分析，则按‘y’键，否则按‘n’键 程序结束-lexical analyzer : the source of the mode of operation : the importation of operational procedures already exist in a text file in the file name. Such as : input.txt if the entire procedure syntax analysis, the provision "y" button, or by the "n" key to the procedure syntax analysis, the provision "y" button, or by the "n" key end of the program
