Answer 1

If you are defining a class and want to define a static variable you are free to declare it into public, private or protected section.
For example :
class test{
private:
static int a;
public:
int inc()
{
a++;
}
void display ()
{
cout << a;
}
};

int main()
{
test t1, t2, t3;
t1.inc();
t2.inc();
t3.inc();
t.display();
}

When you create a object of class, only one copy of static member is generated through the whole code .
