简单的LL（1）的分析，具体可见程序，有过程，一目了然，谢谢指教...

为了实现的编译程序实用，源程序可采用自由书写格式，即一行内可以书写多个语句，一个语句也可以占领多行书写；标识符的前20个字符有效；整数用2个字节表示；长整数用4个字节表示。这样词法分析程序的主要工作为： （1）从源程序文件中读入字符。 （2）统计行数和列数用于错误单词的定位。 （3）删除空格类字符，包括回车、制表符空格。 （4）按拼写单词，并用（种别，单词）二元式表示。 （5）根据需要是否填写标识符表供以后各阶段使用。 这里采用的编译程序的实现方法是一遍扫描，即从左到右只扫描一次源程序，也就是词法分析作为语法分析的一个子程序。故在编写词法分析程序时，用重复调用词法分析子程序取一单词的方法得到整个源程序的二元式流。 -in order to achieve the compiler practical, available free to write source code format, that his writing can be more than words, a statement can occupy multiple lines written; identifier of 20 characters effective; Integer with two byte; long integer with four byte. This lexical analysis for major work : (1) from source document read into the characters. (2) Statistics and a few mistakes out a few words for positioning. (3) delete the blank type characters, including the carriage return, tab spaces. (4) the spelling words and use (other species, words) dual ceremony. (5) whether the need for completing the table identifier subsequent stages. Here the compilers of th

无解压密码,这是一个编译原理的实验源码,已经编译成功能实现读无符号数了.-without extracting passwords, it is a principle of experimental compiler source code, compiler can achieve success without reading a few symbols.

一个c语言写的词法分析器和语法分析器的简单算法，适用于编译原理的初学者-a written language lexical analyzer and parser simple algorithms, compiler theory applies to the beginners

这是一个使用标准 C 开发的简单的可以对 C 语言程序进行语法检查的程序，本程序检查你的程序中小括号、中括号、大括号、单引号、双引号、/* */ 注释等的配对情况，可以及时发现程序中存在的语法错误情况。-This is a standard C development can be a simple C language syntax procedures for the inspection procedures, the procedures check your procedures small brackets, brackets, brackets, the single quotes, double quotes,/**/Notes for the match, found it timely procedures the errors of grammar.

pascal的编译器 交作业没问题 -perpendicular operation of the compiler no problem Haha

JC1.0。本编译器包含完整的文档与程序。借助 Lex & Bison, masm 开发。语句5个，支持混合运算。输入输出作为两个 IO 语句（函数调用），由汇编实现并编译为 io.obj，将由 Link 链接。生成 EXE。整个流程完整清晰，代码易读。-JC1.0. The compiler includes complete documentation and procedures. With Lex Bison, can develop. Statement 5, support mixed computing. Input and output as two IO statement (function call), compiled by the compiler to achieve and io.obj will link Link. EXE generation. The entire process, complete and clear, legible code.

实现词法分析，并用LR0实现语法分析.这是编译原理的实验时候做的。-It realized the lexical analysis and grammatical analysis function, it was written by C++ language.
