一个自动字符处理类

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

这是一个哈夫曼编译器,是我学数据结构的时候老师要求做的一个作业-This is a compiler Huffman, I studied the data structure when the teacher demanded an operations

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

PL/0教学语言的编译程序原代码。-PL/0 teaching language compiler original code.

C编译器,在VC6.0环境下开发，是C的一个简单编译器，但可以运行任何C程序，可以函数嵌套-C compiler, the environment VC6.0 development is a simple C compiler, But can run any C program can be nested function

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
