这是编译原理的词法分析源程序

《编译原理实践教程》中的程序作了一些扩展，可以将程序转化成四元式。 本人认为书上的程序极为垃圾！- "Translation Principle Practice Course" the center procedure has made some expansions, may transform the procedure four Yuan types. Myself think in the book procedure extremely trash!

MIPS32指令系统的汇编器。 在QUARTUS仿真环境中，将MIPS32指令写成的汇编程序翻译成二进制写入指令存储器。-MIPS32 instruction set of the assembler. Simulation environment in QUARTUS will MIPS32 assembler written instructions translated into binary memory write instructions.

用C语言实现了C-程序的语法分析，以控制空格来显示层次，表示出了语法分析树-With the C language to implement the syntax of C-program analysis in order to control the space to show the level of expressed syntax parse tree

一个很好的文本编辑，实现了文本文件的创建、读入、保存。文件内容的修改：字、词、段的插入、删除、修改。文件内容的查找、替换：词，文件内容的Copy、Paste。不使用MFC-a good text editor, the realization of the creation of text files, read, the depositary. The contents of the documents modifications : Words, Phrases and of the insertion, deletion, modification. The content of a document search to replace : word, the contents of the documents Copy, Paste. Do not use MFC

语法分析器，实现pascal语言的分析，对源程序从左到右进行扫描，对组成源程序的字符串拼接成为单词；并把其并把其转换成属性字输出,并管理符号表，处理词法错误。-Parser to realize pascal language analysis, source code is scanned from left to right, to the composition of a string of source code splicing into words and its properties and to convert it into a word output, and manage the symbol table, dealing with lexical错误.

pl 词法分析器，自己编的，输入文件名 （包括后缀）即可-pl morphology analyzer, own arrange, the input filename (decorates including after) then

1、 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。 2、 递归下降分析程序应能发现输入串出错。 3、 设计两个测试用例（尽可能完备，正确和出错），并给出测试结果 -1, input strings should be the output of lexical analysis of binary sequence, that is, the arithmetic expression of a

这几天做编译的课程设计,只做了词法分析部分,感觉很不错!-these days do a translation of the curriculum design, doing some of the lexical analysis, I feel very good!

逆波兰试的翻译程序， 是我的程序作业 - Goes against the Poland trial interpretive program, is my procedure work

自己编的一个小程序，供大家参考，有不足之处请提意见。-A small program is writed by myself,supply with you,please give me opinion.
