在头文件中初始化常量静态数组 [英] Initializing Constant Static Array In Header File

问题描述

我刚刚发现以下内容无效.

I have just found out that the following is not valid.

//Header File
class test
{
    const static char array[] = { '1', '2', '3' };
};

初始化它的最佳位置在哪里?

Where is the best place to initialize this?

推荐答案

最好的地方是在源文件中

The best place would be in a source file

// Header file
class test
{
    const static char array[];
};

// Source file
const char test::array[] = {'1','2','3'};

您可以像尝试那样在类声明中初始化整数类型；所有其他类型都必须在类声明之外初始化，并且只能初始化一次.

You can initialize integer types in the class declaration like you tried to do; all other types have to be initialized outside the class declaration, and only once.
