直接写了

程序代码：

class rectangle
{
    private:
        int length,width,height;
    public:
        void input();
        long volume();
        void print();
}
void rectangle::input()
{
    cout <<"input length,width,height:";
    cin >> length >> width >> height;
}
long rectangle::volume()
{
    return length*width*height;
}
void rectangle::print()
{
    cout << "V=" << rectangle()<< endl;
}

int main()
{
    rectangle rect;
    rect.input();
    rect.print();

    return 0;
}

#include<iostream>
using namespace std;
class rectangle
{
    private:
        int length,width,height;
    public:
        void input();
        long volume();
        void print();
};
void rectangle::input()
{
    cout <<"input length,width,height:";
    cin>>length>>width>>height;
}
long rectangle::volume()
{
    return length*width*height;
}
void rectangle::print()
{
    cout<<"长方体的体积为:"<<volume()<<endl;
}

int main()
{
    rectangle R[3];
    for(int i=0;i<3;i++)
    {
    R[i].input();
    R[i].print();
    }

    return 0;
}
这个是对楼上的补充！
