对C++进行词法和语法分析。 要求： 词法分析部分写出相应的正规集、正规式、NFA、DFA 写出语法分析所采用的方法和完成的语法分析功能...

词法分析程序设计 1、给出各单词符号的类别编码。 2、词法分析程序应能发现输入串中的错误。 3、词法分析作为单独一遍编写，词法分析结果为二元式序列组成的-Lexical analysis program design one, given the various types of code word symbols. 2, lexical analysis procedure should be able to detect errors in the input strings. 3, again as a separate lexical analysis prepared for morphological analysis of binary sequence composed of

这个是编译原理的词法分析的实验报告！很不错，希望大家支持！-this principle is to compile the lexical analysis of the experimental report! Quite well, and hope that we support!

有限自动机的运行，利用状态表和有限自动机的运行原理，识别一个输入串是否为一个有效的无符号定点实数。-of the operation, the use of tables and limited state of the automatic machine operation principle, to identify whether an input string as a symbol of effective non-sentinel real.

NFA转化为DFA的一个程序!希望能有点作用!-NFA into a DFA procedures! Hope to some purpose!

C_minus语言的BNF语法定义 程序由声明的列表(或序列)组成，声明可以是函数或变量声明，顺序是任意的。至少必须有一个声明。接下来是语义限制(这些在C中不会出现)。所有的变量和函数在使用前必须声明(这避免了向后backpatching引用)。程序中最后的声明必须是一个函数声明，名字为main。注意，C－缺乏原型，因此声明和定义之间没有区别(像C一样)。-C_minus BNF language syntax definition of procedures from the list of statement (or sequence), with a statement can be variable or function statement, the order is arbitrary. There must be at least one statement. Next is the semantic constraints (these will not arise C). All the variables and functions to be used in the statement (which avoids the use Backpatching backwards). Procedures must be the last statement is a function declaration, the name of the main. Attention C- lack of a prototype, and the definition of a statement is no difference between (the same as C).
