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.

单词频率统计，再次基础上可以开展更广泛的工作- The word frequency statistics, in the foundation may do a more widespread work once more

编译原理LR(0)文法分析器 录入合法的LR(0)文法，将输出LR(0)分析表，并可以对输入的句子进行语法分析输出相应语法树。 程序中部分算法还很不简洁，有待改进，欢迎朋友与我多多交流。- Translation principle LR (0) grammar analyzer input legitimate LR (0) the grammar, will output LR (0) the analytical table, and will be allowed to carry on the grammar analysis output corresponding grammar tree to the input sentence. In the procedure the partial algorithms very are not succinct, await improvements, welcome the friend and my many exchanges.
