c编译器实现，利用lex yacc写的简单编译器

用C#做的《编译原理》的PROJECT--语法分析器（算符优先法） 文法，句子均支持从TXT文件输入或者手工键入，分析结果可保存为RTF文件-With C# To do the

C编译器源码是我到处找来的,看了之后很有收获-C compiler source is found everywhere, and found the great harvest

这是pascal的词法分析程序- This is the pascal lexical analyaer

用c编写的语法解析器，能进行词法和语法分析-c prepared with the parser can make grammatical and lexical analysis

布尔表达式的翻译- Boolean expression translation

新编的编译原理程序- Newly organized translation principle procedure

用LL（1）法对布尔表达式的语法分析- (1) the law analyzes with LL to the Boolean expression grammar

词法分析,语法分析,文件中有语言的文法,根据文法写出的程序样例,还有根据样例进行词法分析得出的文件-lexical analysis, grammar analysis, the paper is the language grammar, grammar write the program sample, for example under the lexical analysis of documents

词法分析器 对输入的程序进行分析，将关键字，保留字与系统标识符分开，并对其属性进行说明。 建立数组，将单词读入，对单词的ASCII码进行判断，将在ASCII码值在一定区间进行区分（使用if语句来判断），分开来后，对其所在ASCII值区间的不同，给予以不同的属性(比如：系统保留字…），词法分析器完成后要能识别+,-,=等字符。-lexical analyzer on the importation procedures for analysis, keyword, the word reservation system with separate identifier, and a description of their attributes. The establishment of an array, you read the word, the right word ASCII judgment, in ASCII value in a certain area and distinguish between (use to determine if statements), separately, its value lies ASCII range of different, to give a different properties (such as : system retain the word ...), after the completion of a lexical analyzer to identify,-, =, etc. characters.
