In Baker's tool Dup(Baker.B, et al., 1995), lines of source files are first divided into tokens by a lexical analyzer. Tokens are split into parameter tokens (identifiers and literals) and non-parameter tokens, with the non-parameter tokens of a line summarized using a hashing function,...
The main focus of the research targets the functional characteristics and the working mechanism of the compiler through the analysis of prolog language organizing and translating procedure in conjunction with the logic-reasoning attribute of the language. The paper illustrates structure of three important...

c语言实现java词法分析器词法分析器c++语言编写 词法分析器概述词法分析器的本质:基本任务是进行模式匹配,其关键在于分析过程中的模式说明和模式识别方法,在编译分析中即正规表达式和有限自动机。构造词法分析器方法:1、手工构造;2、利用自动生成工具LEX。但是无论用那种方法,其内在工作原理都是相同的,都要经过正规式到...
