摘    要:词法分析器是编译器的第一个组成部分,是后续部分的基础,同时,词法分析也广泛应用在很多软件中,所以理解词法分析器的构造原理比较重要。设计并实现的模拟器能够以表格和图形的方式展示词法分析器的构造过程,并可以形象模拟词法分析器从源程序中识别单词的过程。

关 键 词:词法分析  扫描  模拟

Abstract:Lexical analyzer is the first component of a compiler,and is also the base of the subsequent parts.Meanwhile,lexical analysis is widely applied in a lot of software.Therefore,it's very important to have a good knowledge of the construction principle of the lexical analyzer.The stimulator that is designed and implemented in this paper is able to show the procedure of constructing a lexical analyzer in the way of tables and diagrams,and can visually stimulate the word recognition process of the lexical analys...
Keywords:Lexical analysis Scan Simulation
