编译原理程序之词法分析器- Translation principle morphology of analyzer procedure

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

这是一个此法分析器的手工构造实例，程序很简洁。-This is a method of manual analyzer tectonic example, a very simple procedure.

LL(1)文法使用的是确定的自顶向下的分析技术。LL(1)的含义是：第一个L表明自顶向下分析是从左向右扫描输入串，第2个L表明分析过程中将使用最左推导，1表明只需向右看一个符号便可决定如何推导，即选择哪个产生式(规则)进行推导。-LL (1) grammar using a set top-down analysis techniques. LL (1) the meaning is: the first one L shows a top-down analysis is a scan input string from left to right, the first two L shows the analysis process will be the most left-derivation, one that will be just right to see a sign can decide how to derive, choose what Production (rules) for derivation. LL (1) grammar, followed by calculation of the discriminant needs FIRST sets, FOLLOW sets and SELLECT set, and then determine whether to LL (1) grammar, the last sentence further analysis.

词法分析器：源程序的运行方式： 运行程序 输入一个已存在的文本文档的文件名。如：input.txt 如果要对整个程序进行语法分析，则按‘y’键，否则按‘n’键 如果要对程序进行语法分析，则按‘y’键，否则按‘n’键 程序结束-lexical analyzer : the source of the mode of operation : the importation of operational procedures already exist in a text file in the file name. Such as : input.txt if the entire procedure syntax analysis, the provision "y" button, or by the "n" key to the procedure syntax analysis, the provision "y" button, or by the "n" key end of the program

VC++设计语法编辑器-VC design grammar editor

一个超级经典的词法和语法分析程序（附加源代码）．从词法分析的输出过渡到语法分析-a super classic morphology and syntax analysis program (Additional source code). Lexical analysis from the output transition to the syntax analysis

目标代码生成，从四元式到汇编语言的翻译-object code generation, from four yuan to the compilation-language translation.

我用java写的词法分析器，语法分析器正在做，到时候我传上来共享- I use the morphology analyzer which java writes, the grammar analyzer to do, when the time comes I pass on share
