Class和Struct仅用于数据？

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 ++中使用一个没有真正的优势，结构体和类之间的默认可见性是其成员的默认可见性（结构体默认为public，类默认为私有）。

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).

我个人倾向于喜欢POD类型并使用其他类别的课程。

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