Compilation Principle grammar

对给定的文法消除左递归。- To the grammar which assigns eliminates the left recursion.

语法分析器(C++)源代码＋其详细的课程设计报告 输入的文法可以消除左递归并提取公共左因子求出文法的非终结集合――FIRST和FOLLOW集并对输入的算符优先文法，构造算符优先关系表 -Parser (C++) Source code its detailed report on curriculum design input left recursive grammar can be eliminated and the public left factor extract derived grammar of non-end collection- FIRST and FOLLOW set of the input operator priority grammar, operator precedence relations structure table

make文件自动生成器，可生成多种编译器的make文件-make document automatic production, may produce the many kinds of compilers the make document

词法分析的程序。核心函数是一个状态切换的函数 CAjaxParserDlg::Route。状态切换函数解根据一个 DFA 来对输入的文本进行分析。也就是说，如果你做一个新的DFA，就能分析新的词法。 DFA 的初始化在CAjaxParserDlg::OnInitDialog。- Lexical analysis procedure. The core function is condition cut function CAjaxParserDlg::Route. The condition cut function solution acts according to DFA to come to the input text to carry on the analysis. In other words, if you make new DFA, can analyze the new morphology. DFA initialization in CAjaxParserDlg::OnInitDialog.

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.

综合运用所学知识，集成词法分析、符号表管理等程序的成果，编程实现LR（0）算法-Comprehensive use of the knowledge, integrated lexical analysis, symbol table management, and so the outcome of the procedure, programming the realization of LR algorithm

词法分析程序，很初级的，我们刚刚开编译原理- Lexical analyaer, very primary, we just opened the translation principle

1.The content is too simple 2.Is not a sourcecode or document 3.lost some files 4.Description is not detailed or not correct 5.Compressed file has password 6.Sourcecode duplicate or already exist po
