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. .

词法分析器 对输入的程序进行分析，将关键字，保留字与系统标识符分开，并对其属性进行说明。 建立数组，将单词读入，对单词的ASCII码进行判断，将在ASCII码值在一定区间进行区分（使用if语句来判断），分开来后，对其所在ASCII值区间的不同，给予以不同的属性(比如：系统保留字…），词法分析器完成后要能识别+,-,=等字符。-lexical analyzer on the importation procedures for analysis, keyword, the word reservation system with separate identifier, and a description of their attributes. The establishment of an array, you read the word, the right word ASCII judgment, in ASCII value in a certain area and distinguish between (use to determine if statements), separately, its value lies ASCII range of different, to give a different properties (such as : system retain the word ...), after the completion of a lexical analyzer to identify,-, =, etc. characters.
