由表达式求值说开去

On Expression Evaluation

“本文通过一个算术表达式的求值过程引出了编写程序的基本方法,通过问题小发寻求解得一个过程。在文中讨论了有关中缀表达式和后缀表达式求值的一些基本算法问题,并讨论了有关栈,线性结构,映射结构等基本数据结构。最后讨论了软件设计对于扩展算法功能和实现复杂结构的灵活性的一些思路和方法。”

This article introduced the basic programming method with an expression evaluation. The article discussed some basic algorithms issues on infix expression and postfix expression, and primitive data structures like stack, sequence structure and ping structure. Finally, the article explored some ideas and methods about extend algorithms function and the realization of the flexibility of complex structure in software development.
