GNU的词法/语法分析器bison源码，最新版本bison

NFA转化为DFA的一个程序!希望能有点作用!-NFA into a DFA procedures! Hope to some purpose!

是一个不错的语法分析器,里面实现了语法分析的算法,并判断了一些优先级的控制和对栈的操作.-is a good parser, they achieved the syntax analysis algorithms, and a judgment of priority to the control and operation of the stack.

构造实验一所给文法（应考虑改造）的FIRST集合和FOLLOW集合；构造LL(1)分析表；构造预测分析的总控程序；利用分析表、分析栈和总控程序对源程序进行自上而下的语法分输出整个语法分析过程中栈的变化过程及分析结果，如符合语法规则输出“正确”，否则输出“错误”。 -Experiment to construct a grammar (should consider the transformation) of FIRST and FOLLOW set of the collection construct LL (1) analysis table structural prediction analysis of the master control procedures the use of analytical tables, analyze the stack and the total source code control procedures carried out since the last sub output down syntax parsing process of the whole stack and analysis of the results of the change process, such as the grammatical rules out the " right" , otherwise output " error."

按递归下降方式设计其编译程序，生成PL/0栈式指令代码，然后解释执行。用(a=1)+2*(b=3+4*5)/2+2*a*b-(a=a+5)/ (c=2) 测试-dropped by recursive approach to design their own compiler, generating PL/0 Stack-code instructions, and then the interpretation and implementation. Using (a = 1) 2* (b = 3 4* 5)/2* a* b- (a = 5 a)/(c = 2) Testing

c―语言的句法分析器。读入一个C--语言程序，判断该程序是不是一个合法的C--语言程序-c-language parser. Reading into a C-- Language Program, the judgment that the procedure was not a legitimate C-- Language Program

词法分析器,将输入的字符串识别成c语言的关键字等-lexical analyzer, the input string as c identification of keywords, such as language
