c语言的词法分析器源代码

为你的脚本语言编辑器添加智能感知效果,就像VS开发环境的自动提示一样.-For your scripting language editor to add intellisense effects, like the VS development environment, like the automatic prompts.

算符优先语法分析器，根据算符优先分析法，将表达式进行语法分析，判断一个表达式是否正确。-operator priority syntax analyzer, according to operator priority analysis, expression for syntax analysis, judgment, an expression is correct.

词法分析程序 程序当前目录里自己建立一个文本文档，取名为infile.txt,所有需要分析的程序都写在此文本文档里，程序的结尾以"@"标志符结束。运行词法分析程序，程序结果输出到文件名为outfile.txt的文件中,此文件为自动生成。-lexical analysis Procedure current directory to establish his own version of a document, named infile.txt, all need to analyze the procedures are written in the article of this document, at the end of procedures to "@" signs Fu end. Running lexical analysis procedure, the results of the proceedings output to a file called outfile.txt document, this document is generated automatically.

中山大学编译原理课程的一个实验，根据OPP(算符优先)做的一个表达式计算器。 内有实验的设计文档。 实验要求支持sin,cos,max,min,power,mod,boolean,?:,等运算。 这个代码可以为学习编译原理的同学参考。-Principles of Sun Yat-sen University to compile an experimental course, according to OPP (operator priority) to do an expression calculator. There are experimental design documents. Experimental requirements to support the sin, cos, max, min, power, mod, boolean,?:, Such as computing. This code can be compiled for study and reference principles classmates.

智能的词法分析 ，能任意输入正则表达式，能求出NFA，DFA，minDFA,和最后的匹配情况-Lexical analysis of intelligence, can enter any regular expression can be obtained NFA, DFA, minDFA, and the final match of the situation

编译器很好用，详细-compiler useful, detailed

对于给定的输入串，能够判断识别该串是否为给定文法的句型-For a given input string that can identify the string to determine whether a given grammar of the sentence

编译原理的一个小实例 YACC(Yet Another Compiler-Compiler)是LALR(1)分析器的自动生成工具，它的第一版于70年代初发表，是美国贝尔实验室的软件产品（作者为S.C.Johnson） YACC将一前后文无关文法转换为一LALR(1)分析表,并提供使用该分析表进行语法分析的总控程序yyparse().-compiler principles of a small example of YACC (Yet Another Compiler- Compiler) is LALR (1) the automatic generation analyzer tool, its first edition in the early 1970s, was published in the United States Bell Labs software products (the author S. C. Johnson) will be a before and after YACC grammar unrelated to the text converted to a LALR (1) Analysis Table, and provide analysis of the use of the table for syntax analysis of the total control procedures yyparse ().
