Here is a piece of code.

class st {
	static int x;
	int y;
	public:
		static display() { printf("x = %d\n", x); }
		static increment() { x++; }
};

main()
{
	st::display(); // 1
	st s;
	int st::x = 20;  
	st::display(); // 2
	int st::x = 30;
	st::increment();
	s.display();
}

When I compile and run this code, what should be the value of 'x' at (1)?
At (1) is 'x' already initialized?

With the g++, (1) prints x=30.
What is the effect of st::x=20?

Thanks in advance
