为了实现编译器的实用,可自由编写源代码…
为了实现的编译程序实用,源程序可采用自由书写格式,即一行内可以书写多个语句,一个语句也可以占领多行书写;标识符的前20个字符有效;整数用2个字节表示;长整数用4个字节表示。这样词法分析程序的主要工作为:
(1)从源程序文件中读入字符。
(2)统计行数和列数用于错误单词的定位。
(3)删除空格类字符,包括回车、制表符空格。
(4)按拼写单词,并用(种别,单词)二元式表示。
(5)根据需要是否填写标识符表供以后各阶段使用。
这里采用的编译程序的实现方法是一遍扫描,即从左到右只扫描一次源程序,也就是词法分析作为语法分析的一个子程序。故在编写词法分析程序时,用重复调用词法分析子程序取一单词的方法得到整个源程序的二元式流。
-in order to achieve the compiler practical, available free to write source code format, that his writing can be more than words, a statement can occupy multiple lines written; identifier of 20 characters effective; Integer with two byte; long integer with four byte. This lexical analysis for major work : (1) from source document read into the characters. (2) Statistics and a few mistakes out a few words for positioning. (3) delete the blank type characters, including the carriage return, tab spaces. (4) the spelling words and use (other species, words) dual ceremony. (5) whether the need for completing the table identifier subsequent stages. Here the compilers of th

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.
