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.

编译原理词法分析器,生成二元式的代码！适合于大学计算机科学与技术实验设计。-compiler

c语言的词法分析器源代码-c language morphology analyzer source code

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.

Full support for extended regular expressions (those with intersection and complement); Support for some kinds of cycles in grammar; DFA-based operation; Unicode support; C++ only, requires a modern compiler; Lexical analyzers can be configured to get symbols from any input class (built-in support for std::istream, std::wistream and FILE *); Designed to work with Whale, but can work standalone or interface to other parsers.-Full support for extended regular expressions (those with intersection and complement); Support for some kinds of cycles in grammar; DFA-based operation; Unicode support; C only, requires a modern compiler; Lexical analyzers can be configured to get symbols from any input class (built-in support for std::istream, std::wistream and FILE*); Designed to work with Whale, but can work standalone or interface to other parsers.

一个简单实用的自己编写计算器，非常非常非常好用。-Calculator

用于一个小型表达式输入的简易编译器，c语言版的-For a small input simple expression compiler, c language version of the

专门用来包装virtools文件的另一款工具,很好用的-Dedicated to packaging virtools file another tool, a very good use

basic c compiler 类似于basic语法的脚本-basic c compiler is similar to basic grammar of the script

输入文法，可以实现对非终结符，终结符的判断，最后判断文法。-importation of grammar can be realized by the end of the non-Fu, Fu end of the judgment, the final judgment of grammar.
