编译的作业，对词法的分析分类以及发现错误，希望与大家交流，谢谢指教...

这是我同学做得编译原理――词法分析器，有读源文件，和写目标文件-This is the principle of my classmates to do the compiler- lexical analyzer source file has read, and write the destination file

1．词法分析 设计、编制并调试该C语言子集的词法分析程序，要求结果以二元组形式保存在文件中。-1. Lexical analysis design, develop and debug the C language subset of the lexical analysis procedure that requires results to binary form group to preserve the documents.

H++编译器: 一个仿Pascal语言的编译器-H compiler : an imitation of the Pascal language compiler

这个是对上次S语言词法分析的修改,程序已修改好了.-this is the last S language lexical analysis of the changes, the procedure has been revised up.

很好用的语法分析器。-good with the parser.

C语言编写的简单计算程序的语法分析器，可以识别一定的计算功能-C language prepared by the simple calculation procedure syntax analyzer can identify certain computing capabilities

1、构造该算符优先文法的优先关系矩阵或优先函数； 2、输入串应是词法分析的输出二元式序列，即某算术表达式“实验项目一”的输出结果。输出为输入串是否为该文法定义的算术表达式的判断结果。 3、算符优先分析过程应能发现输入串出错。 -1, construction of the operator the priority of the priority relation matrix grammar or priority function 2, input strings should be the output of lexical analysis of binary sequence, that is, the arithmetic expression of a
