定义几何图形圆的类Circle,包括圆心O(另定义Point(点)

classCircle{private:intm_nR;public:Circle(intnR){m_nR=nR;}floatOutputF(){return2*3.1415926*(float)m_

#include"stdio.h"constdoubleP=3.14;classCircle{public:virtualdoubleArea();voidR(doubles);doublegetr(

以发送,楼主查收

把这三个类分别放到三个.java文件中,然后编译运行即可.publicclassCircle{privatedoubler;publicCircle(doubler){this.r=r;}public

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

#includeusingnamespacestd;classCircle{public:Circle(doubler=0):radius(r){}doubleArea(){return3.14*ra

请看课本

#includeusingnamespacestd;classPoint{public:\x09Point(floatx1=0,floaty1=0)/*Point的构造函数,默认圆点为(0,0)*/\

publicclassCircle{privatedoubleradius;publicCircle(doubler){this.radius=r;}publicstaticvoidmain(Stri

#include <iostream>using namespace std;const double PI = 3.

不要提出这种问题,代码还是自己动手写的好,写的过程中遇到麻烦,再拿出来问的话,我想会有更多人乐意帮你解答的再问：来不及哦！！今天晚上要交！！没时间慢慢写！！我对c++也不是很熟！急求高手流利的给个程序
