Pascal 到C的转换器

c―语言的句法分析器。读入一个C--语言程序，判断该程序是不是一个合法的C--语言程序-c-language parser. Reading into a C-- Language Program, the judgment that the procedure was not a legitimate C-- Language Program

实现NFA确定化子集算法程序。DFA是NFA的特例。对每个NFA 　N一定存在一个DFA　Ｍ ，使得 L(M)=L(N)。对每个NFA N存在着与之等价的DFA M。从NFA的矩阵表示中可以看出，表项通常是一状态的集合，而在DFA的矩阵表示中，表项是一个状态，NFA到相应的DFA的构造的基本思路是：1.DFA的每一个状态对应NFA的一组状态. 2. DFA使用它的状态去记录在NFA读入一个输入符号后可能达到的所有状态.。-achieve NFA Number algorithm to determine procedures. DFA NFA is a special case. NFA N for each must exist a DFA M, makes L (M) = L (N). N for each NFA exist with the DFA M equivalent. NFA from the matrix can be seen, tables are usually set of a state, and in the matrix DFA said, Form is a state of the corresponding NFA DFA basic structure of ideas : 1.DFA each one corresponds to a group of NFA state. 2. DFA use it to the state records in NFA Reading input into a symbol after all reach the state. .

编译原理实践教程PL0语言编译程序源代码。参考书：清华大学出版社的《编译原理》作者吕映芝、张素琴等。 实现主要功能有：对使用PL0语言编写的程序进行词法分析，查看词法分析的结果，语法分析， 生成中间代码并可供查看，以及解释执行。 压缩包中含有实验报告文本，其中有程序中各功能模块及主要功能的详细说明。-Compilation Principle Practice Guide PL0 source language compiler. Reference: Tsinghua University Press, Compiler Construction Principles author Lu Ying-chi, such as Su-Qin Zhang. The realization of the main functions are: the use of language PL0 lexical analysis procedure to see the results of lexical analysis, syntax analysis, intermediate code generation and will also be available to view and explain the implementation. Experimental package contains the text of the report, including detailed description of every functional process modules and main functions.

编译原理的一个小实例 YACC(Yet Another Compiler-Compiler)是LALR(1)分析器的自动生成工具，它的第一版于70年代初发表，是美国贝尔实验室的软件产品（作者为S.C.Johnson） YACC将一前后文无关文法转换为一LALR(1)分析表,并提供使用该分析表进行语法分析的总控程序yyparse().-compiler principles of a small example of YACC (Yet Another Compiler- Compiler) is LALR (1) the automatic generation analyzer tool, its first edition in the early 1970s, was published in the United States Bell Labs software products (the author S. C. Johnson) will be a before and after YACC grammar unrelated to the text converted to a LALR (1) Analysis Table, and provide analysis of the use of the table for syntax analysis of the total control procedures yyparse ().
