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...

C programm for simple Calculator.

c语言编译器源代码，small c for dos源代码，对学习c语言本质很有好处。-c language compiler source code, small c for dos source code, the nature of learning c language is very good.

算符优先语法分析器.-operator priority parser.

1. 构造一小型C语言SimpleC的编译器软件，达到综合理解和运用编译原理课程所讲解的关键过程（词法分析、语法分析、静态语义分析、代码生成）及相关算法的目的。 2. 通过本实验理解和掌握一般编译程序的程序组织方法和测试方法。 -1. Tectonic a small SimpleC the C language compiler software. achieve comprehensive understanding and use of compiler theory courses on the key processes (lexical analysis, grammar analysis, static semantic analysis, Code Generation) and the related purpose of the algorithm. 2. The passage of the experiment to understand and master the general compiler of the methods and procedures for organizations testing methods.

编译原理课程设计，包括词法，语法，语义分析，功能全面！-the class design about principle of complier.it contains analysis of word ,gram and mine about language .

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.

词法分析的源代码- Lexical analysis source code

这是一个PLO的编译器,是编译原理课程设计的一个很好的内容-This is a compiler of the PLO, is to compile the curriculum design principle a good content

自己写的一个C子集的编译程序，包括源码和说明文件，以及文法的扩充BNF表达式-himself wrote a subset of the C compiler, including source code and documentation, and the expansion of BNF grammar expression
