指令式（过程式）编程可能会建议组合使用if或switch条件语句，从而获得顺序正确的应用程序逻辑，但它们并不代表代码的概念，这使得它们变得很难维护。

Imperative ( procedural ) programming might suggest monolithic if or switch conditional statements to properly order application logic , but they fail to represent the concept of the code , making them more difficult to maintain .
