在C ++中什么时候应该使用类和结构体？ [英] When should you use a class vs a struct in C++?

问题描述

在什么情况下，最好在C ++中使用 struct vs ？

In what scenarios is it better to use a struct vs a class in C++?

推荐答案

类与 struct 在C ++中结构有默认 public 成员和基础和类有默认私有成员和基础。类和结构都可以混合使用 public 和 private 成员，可以使用继承并且可以有成员函数。类创建一个命名空间，它还封装了操作其数据元素的函数。类与C接口时不能使用，因为C没有类的概念。

Differences between a class and a struct in C++ are that structs have default public members and bases and classes have default private members and bases. Both classes and structs can have a mixture of public and private members, can use inheritance and can have member functions. Classes create a namespace that also encapsulates the functions for manipulating its data elements. Classes may not be used when interfacing with C, because C does not have a concept of classes.

我建议使用structs作为普通数据结构，没有任何类类似的特征，并且使用类作为具有私有数据和成员函数的聚合数据结构。

I would recommend using structs as plain-old-data structures without any class-like features, and using classes as aggregate data structures with private data and member functions.
