这是个简单的语法分析器程序,输入一个表达式,会给出一个分析过程....

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 ().

一个多线程，多流程的脚本编译解释平台，能够同时运行多份脚本代码，流程可以直接加载任意接口的动态库，执行数据库库访问，存储过程和sql语句，加载支持双接口的com，支持多机通讯，曾用于cti开发，-A multi-threaded, multi-process platform to explain the script compiler that can run multiple copies of the script code, the process can directly interface to load arbitrary dynamic library, the implementation of the database library access, stored procedures and sql statements, support for dual-interface load com in support of multi-machine communications, CTI has been used for development,

这是一个此法分析器的手工构造实例，程序很简洁。-This is a method of manual analyzer tectonic example, a very simple procedure.

Complete support for EBNF notation; Object-oriented parser design; C++ output; Deterministic bottom-up "shift-reduce" parsing; SLR(1), LALR(1) and LR(1) table construction methods; Automatic parse tree creation; Possibility to output parse tree in XML format; Verbose conflict diagnostics; Generation of tree traverse procedures

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

设计、编制并调式一个词法分析程序，加深对词法分析原理的理解,对字符串型单词符号（if,then,while,do----）等等用函数int reserve(char* p)来处理，对单词符号（+，-，*，/，=-----）等等用switch()来处理。-cifafenxi
