考题 ●试题五阅读下列程序说明和C++代码,将应填入(n)处的字句写在答卷的对应栏内。【说明】①在类体中添加函数move(double ax, double ay)的定义,使得点的坐标x和y分别移动ax和ay个单位。②在类定义外完成重载的两个构造函数CPosition()和CPosition(double dx, double dy),其中前者为不带参数的构造函数,使CPosition对象的默认值为x=0,y=0,后者为带参数的构造函数,把数据成员x和y分别初始化为参数dx和dy的值。③完成函数double distance(double bx, double by)的定义,该函数返回*this和点(bx,by)的距离。注意:除在指定的位置添加语句外,请不要改动程序中的其他语句。源程序文件test5.cpp清单如下:#includeiostream.h#include math.hclass CPosition{public:CPosition();CPosition(double dx, double dy);double getx();double gety();(1)double distance(double bx, double by);private:double x;double y;};(2){x=0; y=0;}CPosition::CPosition(double dx, double dy){x=dx; y=dy;}double CPosition::getx(){return x;}double CPosition::gety(){return y;}double CPosition::distance(double bx, double by){(3)}void main(){double a,b;cout "Input x, y position of a point: ";cin a b;CPosition psA(a, b);cout "Input x, y position of another point: ";cin a b;cout "The distance is " psA.distance(a,b) endl;}
