设计有穷自动机FA实现C.doc

设计有穷自动机DFA实现C++简单程序的词法分析、扫描 前面两篇（一、二）只是直 Tiny 源程序C++源程序的DFA的方法来Token。 根据老3种实现方式，前面两篇（一、二）就是属于“直接”这一类，而本文则是“DFA”这一类。 按1）和（5）点。而且第（1）点中有两个要求未能完成： 浮点数，因DFA已“表”（即状 ★ 注 实验中用到的C++源程序与要求如下：2、“样例程序”稍微修改了一下。 ?#includeiostream.h 被改 #include iostream.h，即 iostream.h 是由双引号 而不是尖括号 包 C 的代 DFA 时考虑不全面，忽略了“小于等于 =，大于等于 =，判断 ==，不等于 != ” = ! 这几个特殊字符造成二。 同C++ 中的 IO 有“ 与 ”也可能与上述特殊字符造成歧 unGetNextChar(int step) 与教材中的有所不同，因“步长参数 step”，其迁就 #includelt;iostream.h 中的 与代 和 =?。 其iostream.h也被作 ★ 另外“i = i + 2;”语句： 3、程序中的打印。 ： 4、C++源程序DFA 图大致如下：5、Java） 近来喜Vim的代Vim下的截： loan management (post) review: 1, approval criteria have been implemented; 2, the contract is correct; 3, in line with the contract, payment; 4, no other major cases against loan security;、Reviewed by: date of record form 9: qilu bank borrowing by single years of maximum amount a maximum no-loan borrowers: borrowers: ...
