一个计算器程序，利用了编译原理的知识，可以用来作为一个例子，学习编译原理...

利用 lex 和yacc自动生成C语言子集的词法分析和语法分析程序的源程序-using lex and generates automatic generation of C language subset of lexical analysis and parsing the source code of procedure

解法:对原文法消除左递归,根据消除左递归后的等价文法建立语法树,而后对此语法树 进行后根遍历,即可得到后缀式.- Solution: Eliminates the left recursion to the original grammar, after equal in value grammar establishment grammar tree which eliminates the left recursion, after but the grammar tree carries on the root to spread the calendar regarding this, after then obtains decorates the type

简单的LL（1）的分析，具体可见程序，有过程，一目了然，谢谢指教-simple LL (1) analysis, we can see specific procedure, a process, clear, thank you enlighten

词法分析,语法分析,文件中有语言的文法,根据文法写出的程序样例,还有根据样例进行词法分析得出的文件-lexical analysis, grammar analysis, the paper is the language grammar, grammar write the program sample, for example under the lexical analysis of documents

从一个开源软件中摘取的正则表达式模块，是学习正则表达式、编译原理的好东西。-From an open-source software in the removal of the regular expression module, is to learn regular expressions, compile the principle of good things.

词法分析器，用编译原理知识设计一个词法分析器。此程序运行并且通过。 vc运行-Lexical analyzer, using the principle of knowledge to design a compiler lexical analyzer. This program runs through. vc run

用户输入一个文法，然后再输入，要被分析的字符串，自动进行语法分析，把每一不的分析过程都一一打印出来。直到分析成功或失败。-a user input grammar, and then imported to the string were analyzed automatically syntax analysis, the analysis of each process does not have to print out on January 1. Until the analysis of success or failure.

陈火旺的程序设计语言编译原理，里面是pdf格式的-Chen Huowang the principle of programming language compilers, which are pdf format
