为什么我什至应该考虑在C ++中使用结构？ [英] Why should I even consider using structs in C++?

问题描述

在C ++中声明结构是否有优势？为什么我不应该只创建一个仅包含数据成员的类（即没有方法）？

Is there ever an advantage of declaring a struct in C++? Why shouldn't I just make a class consisting only of data members(i.e. no methods)?

谢谢

推荐答案

当您拥有POD类型时，公开是节省一行...

When you have a POD type where everything is public is saves a line...

struct Color {
    int r;
    int g;
    int b;
};

vs

class Color {
public:
    int r;
    int g;
    int b;
};

对于那些只是笨拙的事物的对象，这也是常见的做法。愚蠢的意思是没有构造函数，运算符，方法。

And it's also common practice for objects which are just dumb containers of things. Dumb meaning no constructors, operators, methods.
