自己编的词法分析程序,含有实验报告,有详细的数据结构和程序流程说明。-own addendum to the lexical analysis procedures, experimental report containing a detailed data structure and program flow note.

本程序不能编译除大小写字母之外的编码 本程序需事先建立字母权值文后件才可运行 本程序从文件中读入文字，编译后写入文件，所以屏幕上不会直接出现答案-not build this program in addition to case-insensitive outside of the coding process required prior to the establishment of the letters after the value of the text pieces can Win OK this program read from the file into the text, compiled into the paper, not directly on the screen appeared the answer

按递归下降方式设计其编译程序，生成PL/0栈式指令代码，然后解释执行。用(a=1)+2*(b=3+4*5)/2+2*a*b-(a=a+5)/ (c=2) 测试-dropped by recursive approach to design their own compiler, generating PL/0 Stack-code instructions, and then the interpretation and implementation. Using (a = 1) 2* (b = 3 4* 5)/2* a* b- (a = 5 a)/(c = 2) Testing

读取BNF表达式和终结符文件，然后生成相应文法的First、Follow集、文法分析表以及冲突表。-BNF expressions and terminator read the file, and then generates the appropriate grammar First, Follow sets, grammar analysis table, as well as conflict table

Tiny Machine的源码，一个简单易学习的-Tiny Machine source code, simple is easy the east which studies east

一个很号用的词法分析程序，望能对想熟悉编译原理的同仁有一定的帮助，谢谢支持-one of the very lexical analysis procedures can look familiar to colleagues compiler theory can help, thank you support

一个C++函数解释器，很好用。-a C function interpreter, a good use.

本程序实现了简单的编译器功能，是用PL0语言编写的，思路明确-This procedure achieved a simple compiler function is PL0 languages, ideas clearly

这个是脚本引擎lua的例程,这是一个嵌入式的袖珍引擎-This is a lua scripting engine of the routine, this is a pocket embedded engine
