设计并测试一个Retangle的矩形类

设计并测试一个Rectangle的矩形类，其属性为矩形的左下角和右上角两个点的坐标，能计算矩形的面积

#include<iostream.h>
class Point
{
private:
int x,y;
public:
Point(int xx,int yy){x=xx;y=yy;}
int getx() {return x;}
int gety() {return y;}
};
class Retangle
{
private:
Point p1,p2;
int area;
public:
Retangle(Point pp1,Point pp2);
void print() {cout<<"This area is:"<<area<<endl;}
};
Retangle::Retangle(Point pp1,Point pp2):p1(pp1),p2(pp2)
{
int lon,high;
lon=p1.getx()-p2.getx();
high=p1.gety()-p2.gety();
area=lon*high;
}
void main()
{
Point p1(2,3),p2(4,6);
Retangle r(p1,p2);
r.print();
}

#include<iostream> using namespace std;

class Rectangle { public : Rectangle() { cout<<"输入右上角的横坐标：";cin>>x1; cout<<"输入右上角的纵坐标：";cin>>y1; cout<<"输入左下角的横坐标：";cin>>x2; cout<<"输入左下角的纵坐标：";cin>>y2; } float area() { return (x1-x2)*(y1-y2); } private: float x1,x2,y1,y2; };

void main()

{ Rectangle s; cout<<"它的面积是："<<s.area()<<endl; } 提示一下：程序有个bug，就是↗的坐标是否大于↙得坐标无法区分...呵呵
