第四周项目3用对象数组操作长方体

#include <iostream>using namespace std;class Bulk{public:    Bulk(double le=1.0,double we=1.0,double he=1.0):legth(le),wedth(we),heigh(he){};    double volume();    double surfacearea();    void display();    void get_vaule();private:    double legth;    double wedth;    double heigh;};double Bulk::volume(){    return legth*wedth*heigh;}double Bulk::surfacearea(){    return (legth*wedth+legth*heigh+wedth*heigh)*2;}void Bulk::get_vaule(){    cout<<"请输入长宽高：";    cin>>legth>>wedth>>heigh;}void Bulk::display(){    cout<<"体积是："<<volume()<<"面积是： "<<surfacearea()<<endl;}int main(){    Bulk b[5]={Bulk(2.3,4.5,6.7),Bulk(1.5,3.4),Bulk(10.5)};     b[4].get_vaule();     for(int i=0;i<5;i++)     {         cout<<"第"<<i+1<<"个"<<"长方体"<<endl;         b[i].display();     }     return 0;}

运行结果：
