该词法分析器是编译原理课程设计时的项目，使用c语言编写，文件夹中的大部分文件都是当时使用的参考文件，文件夹‘词法分析器’为完成的可以直接运行的词法分析器，解压后可以直接运行。

PL/0语言编译程序采用以语法分析为核心、一遍扫描的编译方法。
一．PL/0语言建立一个词法分程序GETSYM（函数）
二．PL/0语言建立一个语法分析程序BLOCK（函数）
三．建立一个解释执行目标程序的函数
内含所有源码和最终实验报告

这是学《编译原理》时的上机实验。可实现对C语言的词法分析，关键字32个，包含了C的绝大部分运算、限界符，主要是对文件进行读、写操作，节省内存消耗，自以为是一个不错的词法分析程序。运行环境为VC＋＋6.0。

本资源内包含C语言词法分析源代码，测试用例，以及详细实验报告，虽然来源于北邮编译原理作业，虽然本例最终没有完全实现C语言的所有词法分析，但是可供初学lex的朋友作为一个实例进行参考。
