这是一个C++的基础程序，要求用类封装，

#include<iostream>
#include<iomanip>
#include"cube.h"
using namespace std;

void cube::setcube(int a)
{
    l=a;
}
int cube::getL()
{
    return l;
}

int cube::getV(int vv)
{
    v=vv*vv*vv;
    return v;
}

int cube::compare(int a, int b)
{
    if(a==b)
        return 0;
    if(a>b)
        return

#include<iostream>
#include"cube.h"
using namespace std;

int main()
{   int v1,v2,v3,v4,a1,a2,a3,a4;
    cube cube1;
    cube cube2;
    cube cube3;
    cube cube4;
    cube1.setcube(5);
    cube2.setcube(6);
    cube3.setcube(5);
    cube4.setcube(4);
    a1=cube1.getL();
    a2=cube2.getL();
    a3=cube3.getL();
    a4=cube4.getL();
    v1=cube1.getV(a1);
    v2=cube2.getV(a2);
    v3=cube3.getV(a3);
    v4=cube4.getV(a4);
    cout<<"V1="<<v1<<","<<"V2="<<v2<<endl;
    cout<<"V3="<<v3<<","<<"V4="<<v4<<endl;
    if(cube1.compare(v1,v2)==0)
        cout<<"The first cube is bigger than the second cube"<<endl;
    else if(cube1.compare(v1,v2)==1)
        cout<<"The first cube is the same to the second cube"<<endl;
    else cout<<"The first cube is samller than the second cube"<<endl;
    if(cube1.compare(v1,v3)==0)
         cout<<"The first cube is the same to the thrid cube"<<endl;
    if(cube1.compare(v1,v4)>0)
         cout<<"The first cube is bigger than the fourth cube"<<endl;
    return 0;
}

1;
if(a<b)
return -1;
}

是做一个水立方，并且能够实现运算符的重载，还能够进行加减乘除的比较

#ifndef CUBE_H
#define CUBE_H

class cube{
public:
    void setcube(int);
    int getL();
    int getV(int);
    int compare(int,int);
private:
    int l;
    int v;

};
#endif
