static functions in a class

1
Consdier the scenario

class A
{
private:
int a;
public:

static void AStatic( A * ptr)

{
ptr->a= 19;

}


} ;

main()
{
A aobj;
A::AStatic(&aobj);




}



This piece of code works
I donot understand how can a private member be accessed directly in the static function
As i think static functions are only for static memebrs adn accessing public data of the object passed is ok
but how cum private data is accesed.

The access rules apply to static members/functions as well, i.e. that static
function has all the right to fiddle with private members, either static or not.
Those access rules are defined at class level, not instantiation level. If both
X and Y are of that same class, X and Y can fiddle with each others' private
members/functions.

kind regards,
