一个用C++编写的C语言词法分析程序，本人在做WEBSPHERE MQ的收发信息时需要对远端发过来的数据进行解析，然后才能确定要发送到哪一个终端，因此写了对词法分析做了一定的研究，也就写了这么一个程序.-prepared by the C language lexical analysis procedures, I do WebSphere MQ the need to send and receive information sent to the remote data analysis, in order to determine where to send a terminal, wrote a pair of lexical analysis done some research, it was such a procedure.

语法分析―在词法分析的基础上分析表达式-syntax analysis-in lexical analysis on the basis of analysis of expression

目的：通过编写简单的YACC程序熟悉YACC词法分析工具的基本用法，及词法分析器的设计思路。编写包括赋值语句、if语句以及含有加合乘运算的表达式等语法结构的pascal子集语言的语法分析器。 功能：程序由两个模块LEX和YACC构成，YACC使用LEX分析后的正规单词输出流-Objective : to prepare a simple procedure with YACC YACC lexical analysis of the basic tools to use, and the lexical analyzer designs. Preparation including assignment if statements containing Addition and multiplication of expressions such as grammatical structure of the pascal subset of the language syntax analyzer. Function : procedures by the two modules constitute LEX and YACC, YACC LEX analysis using the formal word output streams

该文描述了C语言表达式的文法，并由该文法生成算符优先矩阵和算符优先函数，讨论了C语言表达式的特点和文法分析过程。-The paper describes the expression of the C language grammar, grammar generated by the operator priority matrix and operator priority function to discuss the C language features of the expression and grammar analysis.

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.

一个基于C++的语法分析类，可以用来定制自己的编译器 -A class based C++ syntactic analysis, it can be used to build you own compiler
