【摘要】 <正> 1 引言一般来说,领域语言(Domain Specific Language,又称Little Language)是特定于某个领域的需求的描述语言,它提供足够多的语言成分支持该领域中通用的各种概念,使该领域的工作者可以简洁地用它构造领域内的应用程序。设计领域语言的主要目的就是为了简化应用程序开发过程、降低开发代价,同时又保证领域概念的清晰性,使开发过程可靠性高、可维护性强。更多还原

【Abstract】 Based on the idea of domain-specific languages,a little language-ALL is proposed as a response to some problems in teaching "Algorithms and Data Structures". We expect that ALL will help decouple the learning of algorithms and data structures from the learning of programming languages. The definition and implementation of the main elements of ALL are introduced in this paper.更多还原
