在C ++中初始化一个静态成员（数组） [英] Initialize a static member ( an array) in C++

问题描述

我打算创建一个只有静态成员和静态函数的类。成员变量之一是数组。是否可以在不使用构造函数的情况下初始化它？我现在有很多链接错误...

I intended to create a class which only have static members and static functions. One of the member variable is an array. Would it be possible to initialize it without using constructors? I am having lots of linking errors right now...

class A
{
public:
  static char a[128];
  static void do_something();
};

如何初始化[128]？为什么不能像在C中一样直接指定它的值来初始化[128]？

How would you initialize a[128]? Why can't I initialize a[128] by directly specifying its value like in C?

a[128] = {1,2,3,...};

推荐答案

您可以在.cpp文件：

You can, just do this in your .cpp file:

char A::a[6] = {1,2,3,4,5,6};
