编译原理 课件 蛮实用的

目的：通过编写简单的YACC程序熟悉YACC词法分析工具的基本用法，及词法分析器的设计思路。编写包括赋值语句、if语句以及含有加合乘运算的表达式等语法结构的pascal子集语言的语法分析器。 功能：程序由两个模块LEX和YACC构成，YACC使用LEX分析后的正规单词输出流-Objective : to prepare a simple procedure with YACC YACC lexical analysis of the basic tools to use, and the lexical analyzer designs. Preparation including assignment if statements containing Addition and multiplication of expressions such as grammatical structure of the pascal subset of the language syntax analyzer. Function : procedures by the two modules constitute LEX and YACC, YACC LEX analysis using the formal word output streams

词法分析器实现 c语言 - The morphology analyzer realizes the c language

附录A S语言说明 A．1 字符集的定义 3数据类型定义-language A. A definition of the character set of data type definition

这是一个简单的C编译器的词法分析和语法分析。-This is a simple C-compiler of lexical analysis and parsing.

判断a^mba^n m,n=0的字符串- Judges a^mba^n m, the n=0 character string

这是一份实验报告，目的是掌握YACC的使用方法，了解YACC处理二义性的方法。 用YACC等工具生成如下文法表示的表达式对应的计算器 exp->exp + exp | exp - exp| exp * exp |exp / exp |exp ^ exp | - exp |(exp) |NUM 对于输入的表达式，能输出结果。比如: 3 +(4 *5)结果应为23 当出现错误时可以进行错误处理。 -This is a test report, the purpose is to master the use YACC to learn YACC handling of the ambiguity approach. Using tools such as YACC grammar that generates the following expression for the corresponding calculator exp-> exp+ exp | exp- exp | exp* exp | exp/exp | exp ^ exp |- exp | (exp) | NUM expression for the input type, can be output. For example: 3+ (4* 5) the result should be 23 when the error can be error-handling.

我做的不好呀，请大家指教。- I do am not good, asks everybody to advise.
