定义一个point类,并以point为基类创建矩形类,求面积

usingSystem;usingSystem.Collections.Generic;usingSystem.Text;namespaceConsoleApplication1{publicclas

#include#includeclassPoint{private:\x05doublem_x;\x05doublem_y;\x05public:\x05Point()\x05{\x05\x05m_

后面那个没有返回类型的是类的构造函数,构造函数,拷贝构造函数,还有析构函数,这三个类里面的函数都是没有返回值的.（没有显性返回值,其实会返还.这个可以去了解一下,不明白可以算了）.记住这三个特殊的就是

#include <stdio.h>#include <stdlib.h>class Point{private: int _

publicclassPoint{privatedoublex;privatedoubley;publicPoint(){x=0;y=0;}publicPoint(doublex,d

朋友这个是C++的吧!classPoint{private:intm_nX;intm_nY;public://...}classCircle:publicPoint{private:intm_nR;p

importjava.util.*;classTestPoint{publicdoubledistance(Pointp1,Pointp2){returnMath.sqrt(Math.pow(p1.g

我帮你

编写程序：1.\x09定义一个Point类来处理三维点points(x,y,z).该类有一默认的constructor,一copyconstructor,一negate()成员函数将point的x,y

#include#includeusingnamespacestd;classPoint{private:doubleX,Y;public:Point(doublex,doubley){X=x;Y=y

packagecom.lh.test;importjava.util.Random;publicclassPoint{\x05privatedoublex;\x05privatedoubley;\x0

publicclassPoint{privatedoublex;privatedoubley;publicPoint(doublex,doubley){this.x=x;this.y=y;}publi

#includeusingnamespacestd;#definePI3.14classPoint{public:\x09Point():m_x(0),m_y(0){}\x09Point(double

#include#includetypedefstructPoint{doublex,y;}Point;voidmain(){Pointp1,p2;doublek,b;printf("输入点

publicclassPoint{privateintx;privateinty;publicPoint(){}//无参构造器publicPoint(intx,inty){this.x=

这是教程上的经典例子,多看书吧.

//#include#includeusingnamespacestd;classPoint{public:Point(double_x=0,double_y=0):x(_x),y(_y){cout

首先回答第二点,double getDistance(Point p) 这个方法的设计本身的意义就是 this点（本点）到目标点p的距离的平方,p1.getDi

代码就不给你打了,我给你说思路,其实是很简单的.需要两个类,一个Point,一个Test.这两个类,是调用和被调用的关系,Point被Test调用.关系说好了,就是类具体实现的问题.Point.jav
