Class和Struct仅用于数据？ [英] Class vs Struct for data only?

问题描述

在这样的情况下，使用一个类比结构有什么优势吗？
（注意：它只保存变量，不会有函数）

Is there any advantage over using a class over a struct in cases such as these? (note: it will only hold variables, there will never be functions)

class Foo { 
private:   
   struct Pos { int x, y, z };
public:    
   Pos Position; 
};

与

struct Foo {
   struct Pos { int x, y, z } Pos;
};

推荐答案

在c ++中没有真正的优点，在c ++中，结构和类之间的唯一区别是它的成员的默认可见性（structs默认为public，类默认为private）。

There is no real advantage of using one over the other, in c++, the only difference between a struct and a class is the default visibility of it's members (structs default to public, classes default to private).

就个人而言，我倾向于喜欢POD类型的结构，并为其他所有类型使用类。

Personally, I tend to prefer structs for POD types and use classes for everything else.

编辑：litb 在评论中做了一个好点，所以我要在这里引用他：

litb made a good point in the comment so I'm going to quote him here:

一个重要的其他区别是
structs派生自其他
类/ struct public默认情况下，
，而类通过
默认。 >

one important other difference is that structs derive from other classes/struct public by default, while classes derive privately by default.
