#include "stdafx.h"
#include <iostream>
#include "Point.h"

int main(int argc, char* argv[])
{
	Point pt(3,4);
	cout<<pt.cal_dist(Point(10,12))<<endl;
	pt.set_x(6);
	cout<<pt.get_x()<<endl;
	cout<<pt.cal_dist(Point(10,12))<<endl;

	Point const pt_const(1,10);
	//pt_const.set_x(6);
	cout<<Point::center.x<<endl;
	cout<<Point::center.y<<endl;
	cout<<Point::center.get_x()<<endl;
	return 0;
}
