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

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。
