定义 object 类，有 weight 属性及相应的操作函

解：

#include <iostream.h>
class object
{
private:
int Weight;
public:
object()
{
cout << "构造 object 对象" << endl;
Weight = 0;
}
int GetWeight(){ return Weight;}
void SetWeight(int n){ Weight = n;}
~object() { cout << "析构 object 对象" << endl;}
};
class box : public object
{
private:
int Height,Width;
public:
box()
{
cout << "构造 box 对象" << endl;
Height = Width = 0;
}
int GetHeight(){ return Height;}
void SetHeight(int n){ Height = n;}
int GetWidth(){ return Width;}
void SetWidth(int n){ Width = n;}
~box() { cout << "析构 box 对象" << endl;}
};
void main()
{
box a;
}
