什么时候制作类和函数？ [英] When to make class and function?

问题描述

我是编程的初学者，当我开始编写代码时，我才开始编写并解决问题。
我在单个主函数中编写了整个程序。
我不知道什么时候上课和上课。

I am a beginner to programming when I start to code I just start writing and solve the problem. I write whole program in a single main function. I don't know when to make class, and functions.

我读了哪些好书来学习这些概念？

What are good books which I read to learn these concepts?

推荐答案

一个非常普遍的问题，因此只需遵循以下几条经验法则即可：

A very general question, so just a few rules of thumb:

• 代码重用：当您在两个地方有相同或非常相似的代码段时，应将其移至一个函数

• code reuse: when you have the same or very similar piece of code in two places, it should be moved to a function

可读性：如果一个功能跨越屏幕上的单个页面以上，您可能需要将其分解为几个功能

readibility: if a function spans more than a single page on screen, you may want to break it apart into several functions

focus：每个类或功能都应该仅一项特定任务。并非为此目的核心的所有内容都应委托给其他类/函数。

focus: every class or function should do only one specific task. Everything that is not core to this purpose should be delegated to other classes/functions.
