一个小计算器的实现(编译原理),用Lex和bison

bison源代码.bison 是替代yacc的语法分析程序生成器. yacc是 Yet Another Compiler Compiler的缩写. bison又是什么呐 是一个生成可以分析文本文件结构的程序的程序. 用户不用直接编写程序而只用确定好如何分析这些文本文件的规则就可以了. 这种文本结构应用的例子举不胜举, 其中一个就是计算器(calculator).-bison source code. Bison is a replacement generates a syntax analysis program generator. Yacc yes Yet Another Compiler Compiler"s initials. What is the bison Na is a generation of text files can be analyzed the structure of procedures procedures. users need not directly preparation procedures identified only as good Dr analysis of these text files on the rules. This text structure Application examples abound. which is a calculator (calculator).

语法分析.h,对一个文法给以判断所给的句子是不是文法所生成的。- The grammar analysis h, gives the sentence to a grammar which the judgement gives is the grammar produces.

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.
