一，实验目的：通过设计编制调试一个具体的词法分析程序，加深对词法分析原理的理解。并掌握在对程序设计语言源程序进行扫描过程中将其分解为各类单词的词法分析方法。二、实验要求：1.对给定的程序通过词法分析器弄够识别一个个单词符号，并以二元式(单词种别码，单词符号的属性值)显示。而本程序则是通过对给定路径的文件的分析后以单词符号和文字提示显示。2.本程序自行规定：(1)关键字"begin","end","if","then","else","while","write","read","do", "call","const","char","until","procedure","repeat"(2)运算符："+","-","*","/","="(3)界符："{","}","[","]",";",",",".","(",")",":"(4)其他标记 如字符串，表示以字母开头的标识符。(5)空格、回车、换行符跳过。部分程序代码如下：#include "stdio.h"#include "string.h"//----------------------Global Declarition----
