摘要
编译程序可以将源代码翻译成目标代码,在应用程序开发中起着不可估量的作用。在教学过程中,理解如何对表达式求值及符号推导对于解编译程序工作原理具有重要的作用。本文讨论了如何采用类C语言的方式对表达式进行求值及符号推导,对于教学和研究均有促进作用。
Compiler can translate source code into object code, which plays an inestimable role in the development of application pro- grams. In teaching, expression evaluation and sign derivation have vital important roles in understanding the working principle of com- plier. This paper discusses the method of expression evaluation and sign derivation by similar C language and it has promotion effects in teaching and research.
