词法分析程序设计

词法分析―分析关键字，运算符，常数并用动态链表保存结果-lexical analysis-keyword analysis, Operators, constant and dynamic results preservation Chain

查看asn1 ber编码方式的源文件，有多种查看方式-Show asn1 ber encoding the source file, there are several ways to view

一个C语言编译器源代码，外国人写的东东，生成目标代码时需要有masm配合。-a C language compiler source code, written in the Eastern foreigners, generating object code when it can meet the need.

powerbuiler源码，虽然不算好，但也可以-powerbuiler source, although not good, but it can also be used with! !

一个简单的C词法分析器 能识别数字,标志符(关键字,变量)和一些运算符.-a simple C lexical analyzer can identify the number, identifier (keyword, variable), and some Operators.

一个小计算器的实现(编译原理),用Lex和bison-Realize a small calculator (Principle compiler), with Lex and bison

该系统是本人课程设计作业，因为时间关系，只用了两天多的时间编成。所以有很多地方没有得到增强。版本为1.0。现作以下升级。 增加NEW，OPEN版本。 提高输入容错。判断输入的对错。 时间关系，搜索功能为线性搜索，现增强如下：f_search:费氏查找法；btree:二叉树查找法；l_search：线性查找法； r_search：递归折半查找法；zcsear:杂凑碰撞查找法；o_sear:插补查找加强法； 排序是冒泡法，现增强为：heaps:累堆排序；binary：二叉树排序；xieer：谢耳排序；sinsert：插入排序；quicks:快速排序；select:选择排序法； 有时间不仿试试。-f_search: Find Act Fernandez btree: binary tree search method l_search: linear search method r_search: Recursive half Find Law zcsear: Find a hash collision law o_sear: interpolation search Enhancement Act sort is bubbling method are enhanced for: heaps: HEAPSORT tired binary: binary tree sort xieer: Xie ears sort sinsert: Insertion Sort quicks: quick sort select: Select Sort Method

这是编译原理里面用来判断输入的东西是是否是符合数学运算公式-This is the compiler used to determine the principle of which is whether the importation of things are in line with the mathematical formula

自定义简单语法类C语言编译器，具备识别C语言基本语句功能，并生成四元式-Since the definition of simple types of C language syntax compiler, a statement to identify the basic functions of C language and generate quaternion type

c编译器实现，利用lex yacc写的简单编译器-achieved using lex generates write a simple compiler
