Static initialization of object

Question

I have a global object which is declared before main function and a static object inside main.

• Which one of these uses (or do both?) static initialization?
• I've heard that A obj1 is also called static; why is that?

class A { ... };

A obj1;

int main()
{
    static A obj2;
}

Answer 1

obj1 has static storage. It will be initialized when the program starts.

obj2 also has static storage because you said so. It will be initialized when main() executes the first time.
