摘要
本文针对文献〔1〕中布尔表达式文法和语义子程序不能适用于算符优先分析的语法制导翻译法的局限 ,从算符优先分析法和语法制导翻译的定义及本质特点出发 ,提出了一种改进方法 ,实现了算符优先分析制导翻译布尔表达式 .
In the treatise, aiming at the defect of boolean expressions old grammar and old semanteme program that can not be fit for the operator priority analyse directed compiling ,based on operator priority analysings and syntax directed compilings definition and substantial characteristics,we bring forward the improvement , thereby realized the operator priority analyse directed compiling boolean expression.
