private:
static s objs;//with a concrete member object.
s(){}
s(const s&);
s& operator=();
public:
static s& Create(){return objs;}
....
};
class A{
private:
A objA;//error!
public:
A(){}
};
why, non-static member object type can not be the class itself, but static can?
or my observation is wrong?
my reasoning is that: static is NOT part of the class s (in terms of memory initilization), the static concrete member object only use the class s as a namespace and class s only constraints t | t****t
