词法分析器

基于libboost_regex的正则表达式测试程序，可用于入门者的参考代码。-Libboost_regex regular expression-based test procedure can be used for a reference code for beginners.

语法分析器，实现pascal语言的分析，对源程序从左到右进行扫描，对组成源程序的字符串拼接成为单词；并把其并把其转换成属性字输出,并管理符号表，处理词法错误。-Parser to realize pascal language analysis, source code is scanned from left to right, to the composition of a string of source code splicing into words and its properties and to convert it into a word output, and manage the symbol table, dealing with lexical错误.

这是一份实验报告，目的是掌握YACC的使用方法，了解YACC处理二义性的方法。 用YACC等工具生成如下文法表示的表达式对应的计算器 exp->exp + exp | exp - exp| exp * exp |exp / exp |exp ^ exp | - exp |(exp) |NUM 对于输入的表达式，能输出结果。比如: 3 +(4 *5)结果应为23 当出现错误时可以进行错误处理。 -This is a test report, the purpose is to master the use YACC to learn YACC handling of the ambiguity approach. Using tools such as YACC grammar that generates the following expression for the corresponding calculator exp-> exp+ exp | exp- exp | exp* exp | exp/exp | exp ^ exp |- exp | (exp) | NUM expression for the input type, can be output. For example: 3+ (4* 5) the result should be 23 when the error can be error-handling.

用C语言编的一个小解释器，可以执行C程序的！算是可以执行C程序的C程序吧！ （大师）写的哦！- A small interpreter arranges which with the C language, may carry out the C procedure! Is may carry out C the procedure C procedure! (Master) writes oh!
