有用，非常得有用。

中缀表达式转换成后缀表达式算法，并求算术表达式的方法。-Infix expression into the expression suffix algorithm, and methods for arithmetic expressions.

本工具提供一个词法分析器和语法分析器的集成开发环境，同时提供与其他C程序编译器连接的接口，使用相当方便-The Tool provide an IDE for Syntactic and phrase parser,also provide interfaces for other c comiler, which is very convenient

编译原理―LL(1)文法分析器(1.0) 求LL(1)文法的FOLLOW集合工具： 软件读入一个LL(1)文法，生成其FOLLOW集合。-compiler theory-LL (1) grammar analyzer (1.0) for LL (1) grammar FOLLOW Set tools : software read an LL (1) grammar, generating its FOLLOW pool.

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

本程序是用c#写的一个编译器，实现了词法，语法，语义分析和中间代码生成，输出结果功能-This procedure is used c# Write a compiler, the realization of the lexical, syntax, semantic analysis and code generation between, the output function

编译原理的FOR循环语句的翻译，中间代码生成，以及语法，词法分析等-compiler principles FOR cycle statement to the translation, intermediate code generation, as well as grammar, lexical analysis

编译原理PLO语言的功能扩展C语言源程序-Compilation Principle PLO language extensions C language source code

c编译器包括目标码生成-c compiler code generation, including goals

windowns 环境的lex和yacc编译器工具-windowns environment lex and yacc compiler tool

词法分析的程序。核心函数是一个状态切换的函数 CAjaxParserDlg::Route。状态切换函数解根据一个 DFA 来对输入的文本进行分析。也就是说，如果你做一个新的DFA，就能分析新的词法。 DFA 的初始化在CAjaxParserDlg::OnInitDialog。- Lexical analysis procedure. The core function is condition cut function CAjaxParserDlg::Route. The condition cut function solution acts according to DFA to come to the input text to carry on the analysis. In other words, if you make new DFA, can analyze the new morphology. DFA initialization in CAjaxParserDlg::OnInitDialog.
