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

一个编译器 包括词法分析和语义分析 是课程设计 有要借鉴的同学可以参考-a compiler including lexical analysis and semantic analysis of the design of the curriculum to learn from the students can refer to

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

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.

又一个Pascal 到C的转换器 -Another Converter from Pascal to C

编译器很好用，详细-compiler useful, detailed

表达式的计算程序- Expression computational 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)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.

用C写的简易C编译器-C write simple C compiler

编译原理课程设计，输入布尔表达式，然后有系统自动转换为逆波兰四元式-compiler theory of curriculum design, the importation of Boolean expressions, and then the system automatically converted to reverse Poland four yuan-
