编译原理之词法识别 利用有限自动机识别词法 初始化保留字表和标示符表，识别非法字符-Compiler theory of lexical identification using finite automata recognize lexical reserved words table and initialize the table identifier to identify illegal characters

一款编译原理中的词法分析器，利用有限状态机的机制，能够解析C语言代码的词法结构，将每一个句子变成一个一个单词的形式。-A lexical analyzer in the compiler theory, finite state machine mechanism, able to resolve the lexical structure of C language code, each a one-word sentence into a form.

编译原理文法输入，并根据输入的文法设计有穷状态自动机，判断是否未确定的，若否，则确定化！-Input grammar compiler theory and design of the input grammar finite state machine to determine whether the undetermined, and if not, determine the technology!
