C++版 词法分析、语法分析器-C version of lexical analysis, grammar analyzer

有限自动机的运行，利用状态表和有限自动机的运行原理，识别一个输入串是否为一个有效的无符号定点实数。-of the operation, the use of tables and limited state of the automatic machine operation principle, to identify whether an input string as a symbol of effective non-sentinel real.

编译原理的词法分析程序-compiler tenets of lexical analysis procedure

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!

flex，词法自动生成工具，他可以在极短时间内帮助产生编译器的词法c源程序-flex, automatically generated lexical tools in a very short time he can help the compiler generate c source of lexical

一个可以生成java代码的语法生成器- May produce the java code the grammar production

trigonometri program that I write in C-trigonometri program that I write in C++

LL（1）分析 写的语法分析程序，但是不能实现消除左递归，提取公因子-LL (1) analysis of written grammar analysis program, but can not eliminate the left recursion, extracting common factor

输入已经消除左递归的以及提取公共左因子的LL(1)文法，再输入相应的表达式，若分析成功，则在递归输出过程中输出"acc",若不成功，则有相应的报错以及位置指名。注意，要把同一个非终结符的产生式分成单个输入。他会自动计算first,follow,预测分析表的构造，但并不输出。-importation has been eliminated and left recursive public from the left-LL (1) grammar, further importation of the corresponding expression, if the analysis is successful, the output of the recursive process output "belongs", if successful, there were errors and the corresponding location named. Attention, we should end with a non-escalation of production into a single input. He will be automatically calculated first, follow, and predicting and analyzing the table structure, but does not export.
