大学课程设计之编译原理 词法分析

c-词法分析器，实现了词法分析和简单的语法token提取功能-C minus analysis

本程序是用c#写的一个编译器，实现了词法，语法，语义分析和中间代码生成，输出结果功能-This procedure is used c# Write a compiler, the realization of the lexical, syntax, semantic analysis and code generation between, the output function

编译原理实验中的yacc源码，是一个基于小类C语言的yacc程序，有助于学习yacc的编写。-principle experiment compiler generates the source code, is based on a subset of the C language yacc procedures, contribute to the preparation of learning yacc.

用C++编写的一个简单C语言词法分析器，把需要分析的内容保存在C:input.txt，分 析完毕好保存在C:output.txt-Using C++ to prepare a simple C language lexical analyzer, the need to analyze the contents stored in C: input.txt, finished the analysis of well preserved in the C: output.txt

Java形式文法-BNF.是设计形式文法的好范例。-Java form grammar-BNF. Form design is a good example of grammar.

对于dos下asm编程的初学者很有帮助，只需用到两个应用程序。-For asm programming under dos helpful for beginners, simply use two applications.

语法分析器 能够对输入的数据进行判断 进行分析 判别输入字符串的各种信息

大学期间写的一个简单的词法分析器,通过输入符合自定义语法规则的程序,得到分析的二元组-University wrote a simple lexical analyzer through importation from the definition of the rules of grammar procedures, the analysis of binary Group

C_minus语言的BNF语法定义 程序由声明的列表(或序列)组成，声明可以是函数或变量声明，顺序是任意的。至少必须有一个声明。接下来是语义限制(这些在C中不会出现)。所有的变量和函数在使用前必须声明(这避免了向后backpatching引用)。程序中最后的声明必须是一个函数声明，名字为main。注意，C－缺乏原型，因此声明和定义之间没有区别(像C一样)。-C_minus BNF language syntax definition of procedures from the list of statement (or sequence), with a statement can be variable or function statement, the order is arbitrary. There must be at least one statement. Next is the semantic constraints (these will not arise C). All the variables and functions to be used in the statement (which avoids the use Backpatching backwards). Procedures must be the last statement is a function declaration, the name of the main. Attention C- lack of a prototype, and the definition of a statement is no difference between (the same as C).
