编译原理词法分析的一个小代码

一个语法分析程序,C++写的,内含原码和exe文件. 开发工具:DEV-C-a program of parsing,write in c++,which include original code and exe file.develope tools:DEV-C

实现编译，对编译的文件察看-achieve compiler to compile the documents inspected

vc做的C语言编译器，基本可以编译c的各种特性，值得学习编译器的朋友下载-vc do C language compiler, which can be compiled c various properties worth learning compiler downloaded to see friends

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)文法的判别需要依次计算FIRST集、FOLLOW集和SELLECT集,然后判断是否为LL(1)文法,最后再进行句子分析。 -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.

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

词法分析程序.我自己编程的词法分析程序．很好用-Lexical analysis program

这是我们学校平时实习的四个内容：词法分析、递归下降子程序、ll1语法分析、lr0语法分析 是我用c++编写的。-This our peacetime training schools of the four elements : lexical analysis, recursive decline subroutine, ll1 syntax analysis, lr0 syntax analysis is used c prepared.

按递归下降方式设计其编译程序，生成PL/0栈式指令代码，然后解释执行。用(a=1)+2*(b=3+4*5)/2+2*a*b-(a=a+5)/ (c=2) 测试-dropped by recursive approach to design their own compiler, generating PL/0 Stack-code instructions, and then the interpretation and implementation. Using (a = 1) 2* (b = 3 4* 5)/2* a* b- (a = 5 a)/(c = 2) Testing
