将枚举放在cpp程序中的哪里? [英] Where to put the enum in a cpp program?

问题描述

我有一个使用枚举类型的程序.

I have a program that uses enum types.

enum Type{a,b,};


class A
{
 //use Type
};
class B
{
  // also use that Type
};

2个类位于2个不同的文件中.我应该将类型定义放在头文件中还是在每个班级的班级定义中?

2 class are located in 2 different files. Should I put the type definition in a headfile or in class definition for each class?

推荐答案

如果枚举将在多个.cpp文件中使用，则应将其放在每个文件都将包含的头文件中.如果有通用的头文件，则应使用该文件，否则也可以为此枚举创建一个新的头文件

If the enum is going to be used in more than one .cpp file, you should put it in a header file that will be included by each. If there's a common header file, you should use that, otherwise you may as well create a new header file for this enum
