拿出这个程序来主要是因为原文中只有一个LEX程序,- Puts out this procedure to come mainly is because in the original text only has a LEX procedure,

一个简单的词法分析器，1代表字符，2代表关键字（命令字），4带表算符界符， 注：要把wangs.txt这个文件放在桌面上，然后在这个TXT里写上你要识别的语句。然后保存后关毕，在运行WANG词法分析.EXE进行词法分析。 完成识别后，会在相应的词面前出现以上代号。暂不能对数字进行识别。因为在某种请况下数字也可表是为字符……稍有困难，但完成老师的针对程序段：area=b+c*d。那简直是小菜一碟。-a simple lexical analyzer, a representative character, the two representatives keyword (command word), with four tables operator sector website Note : The wangs.txt the document on the desktop, then the TXT Lane write you to identify words. Then preserved customs Albert, running WANG lexical analysis. EXE for lexical analysis. After completing the identification, in the appropriate words appear in front of the above code. Provisional figures for the right not to identify. Because of the status of requests under certain figures might be for the characters ... the slightest difficulty, but the completion of procedural teachers : area = b, c* d. It is simply to touch.

编译原理程序,请多指教。- The translation principle procedure, please much advises.

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.

1、给出各单词符号的类别编码。 2、词法分析程序应能发现输入串中的错误。 3、词法分析作为单独一遍编写，词法分析结果为二元式序列组成的中间文件。 4、设计两个测试用例（尽可能完备），并给出测试结果。 -1, given the various types of code word symbols. 2, lexical analysis procedure should be able to detect errors in the input strings. 3, again as a separate lexical analysis prepared for morphological analysis of binary sequence consisting of between documents. 4, the design of the two test cases (as far as possible, complete), and gives test results.
