考题 ●试题六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】源程序中定义了Circle类与Money类,Circle类可对半径为r的圆进行周长与面积的计算,而Money类用于计算一圆形游泳池的造价。游泳池四周有原形过道,过道外围上栅栏,过道宽度为3米,根据键入的游泳池半径,每米栅栏价格及每平方米过道价格,即可计算出游泳池的造价。请按要求完成下列操作,将程序补充完整。①定义符号常量PI(值为3.14159f)与WIDTH(值为3.00f),分别用于表示圆周率与过道的固定宽度。②定义Circle类默认构造函数,把私有成员radius初始化为参数r的值。③完成Money类默认构造函数的定义,把私有成员FencePrice(每米栅栏的价格)、 ConcretePrice(每平方米过道的价格)初始化为参数f,c的值。④完成Money类成员函数float Money::TotalMoney(float fencelen, float conarea)的定义,根据参数fencelen(栅栏的长度)和conarea(过道的面积),返回栅栏与过道的总造价。注意:除在指定位置添加语句之外,请不要改动程序中的其他内容。源程序文件test4.cpp清单如下:#include iostream.h(1)class Circle{private:float radius;public:(2)float Circumference(){return 2 * PI * radius;}float Area(){return PI * radius * radius;}};class Money{private:float FencePrice;float ConcretePrice;public:Money(float f,float c);float TotalMoney(float fencelen, float conarea);};Money::Money(float f,float c){(3)}float Money::TotalMoney(float fencelen, float conarea){(4)}void main(){float radius,fence,concrete;cout.setf(ios::fixed);cout.setf(ios::showpoint);cout.precision (2) ;cout "Enter the radius of the pool: ";cin radius;cout "Enter the FencePrice: ";cin fence;cout "Enter the ConcretePrice: ";cin concrete;Circle Pool(radius);Circle PoolRim(radius + WIDTH);Money mon(fence,concrete);float totalmoney=mon.TotalMoney(PoolRim.Circumference(),(PoolRim.Area() - Pool.Area()));cout "The total money is RMB " totalmoney endl;}
