一个超级经典的词法和语法分析程序（附加源代码）．从词法分析的输出过渡到语法分析...

构造LR(1)分析程序，利用它进行语法分析，判断给出的符号串是否为该文法识别的句子，了解LR（K）分析方法是严格的从左向右扫描，和自底向上的语法分析方法。-tectonic LR (1) analysis procedure, and use it for syntax analysis, judgment, given the string of symbols to whether the sentence grammar recognition, understanding LR (K) analysis method is strict scan from left to right, and bottom-up syntax analysis.

编译原理练习题与答案主要是词法分析、语法分析、中间代码等相关习题与答案.-compiler theory and practice that the answer is lexical analysis, parsing, intermediate code, and other related exercises with answers.

DES算法完整源码与调用方法 DES算法完整源码与调用方法-DES algorithm for complete source code to call methods of DES algorithm with complete source code and call the method

实现NFA确定化子集算法程序。DFA是NFA的特例。对每个NFA 　N一定存在一个DFA　Ｍ ，使得 L(M)=L(N)。对每个NFA N存在着与之等价的DFA M。从NFA的矩阵表示中可以看出，表项通常是一状态的集合，而在DFA的矩阵表示中，表项是一个状态，NFA到相应的DFA的构造的基本思路是：1.DFA的每一个状态对应NFA的一组状态. 2. DFA使用它的状态去记录在NFA读入一个输入符号后可能达到的所有状态.。-achieve NFA Number algorithm to determine procedures. DFA NFA is a special case. NFA N for each must exist a DFA M, makes L (M) = L (N). N for each NFA exist with the DFA M equivalent. NFA from the matrix can be seen, tables are usually set of a state, and in the matrix DFA said, Form is a state of the corresponding NFA DFA basic structure of ideas : 1.DFA each one corresponds to a group of NFA state. 2. DFA use it to the state records in NFA Reading input into a symbol after all reach the state. .
