供大家使用~~打一次哈，不知道好不好，欢迎指导和学习。

我做的不好呀，请大家指教。- I do am not good, asks everybody to advise.

语法分析器 完成从c/c++向C++转变-parser from complete c/c to C change

一个经典的词法分析器，可解析各种复杂的SQL语句- A classical morphology analyzer, may analyze each kind of complex SQL sentence

c语言编译器源代码，small c for z80源代码，对学习c语言本质很有好处。-c language compiler source code, small c for z80 source code, the nature of learning c language is very good.

一个简单的类C语言的编译器的实现 可以参考学习编译原理的基本实现-a simple C-like programming language compiler can refer to the realization of the principle of learning basic compiler to achieve

this is about a script

一个小型的C++代码解释器，可以运行简单的C++代码。-A small C++ code interpreter, you can run a simple C++ code.

语法分析的功能： 语法分析是编译过程的核心部分，它的主要任务是按照和程序语言的语法规则，从由词法分析输出的源程序符号串中识别出各类语法分析成分，同时进行语法检查，为语义分析和代码生成作准备。 有报告-Parsing functions: syntax analysis is the core of the compiler process, its main tasks and procedures in accordance with the grammatical rules of language, from the output by the lexical analysis of source symbols to identify all types of string parsing components, at the same time syntax checker for semantic analysis and code generation to make preparations. There are reports

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.
