Description: （1） 将此番分析程序设计成独立一遍扫描源程序的结构。词法分析的输出结果采用如下的二元组表示：
（单词种别，单词自身的值）
对表识符，采用下列的二元组表示：
（表识符，指向标识符表项的指针）
单词种别建议采用一个关键字一个整数值、一个算符一个整数值等形式，每个整数值是不重复的，设计中应考虑好编码的方案（要跟语法分析连贯）。
（2） 测试用例：
应该建立至少两个测试用例：一个词法上正确的PL/0源程序和词法上部正确的源程序。
-(1) This analysis program will be designed as an independent source to scan the structure again. Lexical Analysis of the output of the dual use of the following group, said: (the word of other species, the value of their own words) on the table knowledge Fu, using the following binary group, said: (Table numeracy Fu, point identifier table entry pointer) word other species suggested an integer value of a keyword, an operator the form of an integer value, each integer value is not repeated, the design should be considered a good encoding program (with grammar analysis of coherence). (2) test case: It should be the establishment of at least two test cases: a lexical correct PL/0 source and the upper part of the correct morphology of the source. Platform: |

Description: 实验一：设计SAMPLE语言的词法分析器
检查要求：
启动程序后，先输出作者姓名、班级、学号（可用汉语、英语或拼音）；
请求输入测试程序名，键入程序名后自动开始词法分析并输出结果；
输出结果为单词的二元式序列（样式见样板输出1和2）；
要求能发现下列词法错误和指出错误性质和位置：
非法字符，即不是SAMPLE字符集的符号；
字符常数缺右边的单引号（字符常数要求左、右边用单引号界定，不能跨行）；
注释部分缺右边的界符*/（注释要求左右边分别用/*和*/界定，不能跨行）。-Experiment 1: SAMPLE language lexical analyzer design
Inspection requirements:
After starting the program, the first output of the author s name, class, student number (available in Chinese, English or Pinyin)
Request input test program name, type the program name and automatically start the output of lexical analysis
Binary output of word-type sequence (see sample output style 1 and 2)
Requirements can be found in the following lexical errors and that the nature and location of the error:
Illegal characters, that is not the character set of symbols SAMPLE
Character constant lack of the right single quotation mark (character constants requires the left and right single quotation mark definition, can not cross)
Note lack of the right part of the boundary character*/(Note requires left and right respectively /* and*/define, can not cross). Platform: |
