哈暗影欢迎指导，打一次 ，不知道好不好。-Kazakhstan shadow welcome guidance, a fight, do not know well or not.

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

中山大学编译原理课程的一个实验，根据OPP(算符优先)做的一个表达式计算器。 内有实验的设计文档。 实验要求支持sin,cos,max,min,power,mod,boolean,?:,等运算。 这个代码可以为学习编译原理的同学参考。-Principles of Sun Yat-sen University to compile an experimental course, according to OPP (operator priority) to do an expression calculator. There are experimental design documents. Experimental requirements to support the sin, cos, max, min, power, mod, boolean,?:, Such as computing. This code can be compiled for study and reference principles classmates.

从网上下载lex工具源代码，并对其进行反复修改 使其能按我们的要求对C程序进行词法分析，然后输出我们期望的结果 -downloaded from the Internet tools lex source code, and it has repeatedly revised to enable it to us by the requirements of the C procedures lexical analysis, and then output the results we expect

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

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,

一个不可多得的Z80为目标机的编译器源程序，是学习编译原理和进行实践的好资料 -A rare Z80 target machine compiler source, is to learn theory and practical experience to compile a good information

现将本人搜集常用的程序设计语言的词法和形式文法提供给大家。其中，词法是按LEX格式编辑，形式文法是按YACC格式书写，大家可直接用LEX和YACC工具编译生成各类程序设计语言的分析器。-commonly used programming language syntax and grammar forms to the public. Among them, morphology is based on LEX format editing, grammar form is written by YACC format, we can use the LEX and YACC tools various compiler generation programming language analyzer.
