C++ 如何在c+；中初始化大量静态类+；

我有头球

Class A
{
int var_1;
int var_2; 
};
Class b
{
private: static A var[MAX];
.....
};

---

但是如何在header.cpp中初始化此属性

提供一个默认构造函数，将int设置为0s或其他值

---

ab:：var[MAX]={}
假设存在不带参数的公共构造函数（或默认构造函数）的
类A
：

文件b.h:

文件b.cpp：

在实现文件中：

A b::var[] = {}; // static member definition
                 // A() is called for each member so you might want
                 // to implement it

例如：

#define MAX 10

class A
{
    int var_1;
    int var_2; 
};
class b
{
private: 
    static A var[MAX];   // static member declaration
};

A b::var[] = {};         // static member definition

int main() {
    return 0;
}

正确吗？你有什么不合适的开始吗？什么样的命名是“header.cpp”？！
A b::var[] = {}; // static member definition
                 // A() is called for each member so you might want
                 // to implement it

#define MAX 10

class A
{
    int var_1;
    int var_2; 
};
class b
{
private: 
    static A var[MAX];   // static member declaration
};

A b::var[] = {};         // static member definition

int main() {
    return 0;
}
