如何在函数中定义一个类的静态成员？

Question

这里我有：

class X { 

public: 
    static int shared_arr[]; 
    static void alloc_and_init() { 

     // Since any static variables defined in the function are allocated some space. 
     // So can I define X::shared_arr here (using the space the static variable for X::shared_arr)? 
     // I think it would be a convenient way to make an approach of some basic memory allocation and initialization. 
    } 

};

没有，你将有只有一个CPP文件&任何功能之外来定义它。

int X::shared_arr[MAX_SIZE] = {0};

请注意，您缺少数组类型。
