用对象数组操作长方柱体类

#include <iostream>
using namespace std;
class BULK
{
public:
    BULK(double a=1.0,double b=1.0,double c=1.0):length(a),width(b),heigth(c){}
    void getvalue();
    void bmj();
    void tiji();
private:
    double length,width,heigth;

};
void BULK::getvalue()
{
    cin>>length>>width>>heigth;
}
void BULK::bmj()
{
    cout<<(length*width*2+width*heigth*2+heigth*length*2)<<endl;
}
void BULK::tiji()
{
    cout<<length*width*heigth<<endl;
}

int main()
{
    BULK b[5]={BULK(2.3,4.5,6.7),(1.5,3.4),(10.5)};
    b[4].getvalue();
    int i=0;
    for(i=0;i<5;i++)
    {
        b[i].bmj();
        b[i].tiji();
    }

    return 0;
}
