C/C++_两种函数不能重载的情况

#include <cstdio>
#include <iostream>

using namespace std;

		this->x = 10;
		this->y = y;

		this->y = 10;
	}
	~KK(){

	int x;
	int y;
	void print(){
		cout << x << endl << y << endl;
	}
}*LPPoint, Point;

int main(){
	LPPoint pt = (LPPoint)(new Point(3));

	pt->x = 5;
	pt->y = 5;

	pt->print();

	cout << sizeof(Point) << " " << sizeof(int) << endl;
	delete pt;

	return 0;
