Structs与C ++中的类 [英] Structs vs classes in C++

问题描述

在C ++中什么时候应该使用structs而不是类，反之亦然？我发现自己使用结构体，当一个成熟的类管理一些信息似乎过分，但想表明包含的信息都是相关的。我想知道什么是一些很好的指导方针，以便能够告诉何时比另一个更合适？

在阅读材料时找到这些链接在提交问题后，显示的堆栈溢出相关：

从技术上讲，两者之间的唯一区别是结构是public的：默认情况下和类是private：

p>除此之外，没有技术上的差异。

struct vs class则成为语言的纯粹表达的细微差别。

通常，避免将复杂的方法放在结构中，大多数时候structs数据成员将保持公开。

$ b

struct = data是非常简单的辅助方法

class =强封装，仅通过方法

When should someone use structs instead of classes or vice versa in C++? I find myself using structs when a full-blown class managing some information seems like overkill but want to indicate the information being contained are all related. I was wondering what are some good guidelines to be able to tell when one is more appropriate than the other?

Edit: Found these links while reading the material Stack Overflow indicated was related after the question was submitted:

When should you use a class vs a struct in C++?
What are the differences between struct and class in C++

解决方案

Technically, the only difference between the two is that structs are public: by default and classes are private:

Other than that, there is no technical difference.

struct vs class then becomes a purely expressive nuance of the language.

Usually, you avoid putting complicated methods in a struct, and most of the time structs data members will stay public. In a class you want to enforce strong encapsulation.

struct = data is public, with very simple helper methods

class = strongly encapsulated, data is modified / accessed only through methods
