本代码为根据老师的课程设计要求做的小编译器的词法分析部分和语法分析部分，附件中有老师的要求文档，还有语法分析时使用到的分析表...

flex，词法自动生成工具，他可以在极短时间内帮助产生编译器的词法c源程序-flex, automatically generated lexical tools in a very short time he can help the compiler generate c source of lexical

这个是编译原理的词法分析的实验报告！很不错，希望大家支持！-this principle is to compile the lexical analysis of the experimental report! Quite well, and hope that we support!

是用flex分析pl0源代码的程序，统计处其中所有的关键字和变量名称，这个rar文件中有readme，具体见其中的说明。另外还有2个测试文件ceshi1.pl0和ceshi2.pl0-is flex pl0 source code analysis procedures, the Census and Statistics Department in which all the keywords and variable names, the rar a readme file, as shown in the note. Another two tests and documents ceshi1.pl0 ceshi2.pl0

C编译器源码是我到处找来的,看了之后很有收获-C compiler source is found everywhere, and found the great harvest

LEX词法分析器-LEX morphology analyzer

用vc编写的一个词法分析源程序，可以对输入的C语言语句进行种别分类-vc prepared with a lexical analysis of the source, can be imported to the C language statements for other species classification

词法分析，LL1语法分析，语义分析，中间代码生成，中间代码优化（常表达式优化，公共表达式优化，循环不变式优化），中间代码生成目标代码，目标代码的解释执行，详细地阐述了一个编译器的设计和实现.-lexical analysis, LL1 syntax analysis, semantic analysis and code generation and code optimization (regular expression optimization, public expression optimization, optimization loop invariant), intermediate code generated object code, object code to explain the implementation of a detailed exposition of a compiler the design and implementation.

编译器，解释器构造，词法、语法、语义分析-interpreter
