希望达人赐教一下
class Cat
{
public:
Cat();
Cat(const Cat&);
~Cat();
int const GetAge()
{
return *itsAge;
}

int const GetWeight()
{
return *itsWeight;
}

void SetAge(int age)
{
*itsAge=age;
}

private:
int *itsAge;
int *itsWeight;
};

Cat::Cat()
{
itsAge=new int;
itsWeight=new int;
*itsAge=5;
*itsWeight=3;
}

Cat::Cat(const Cat & rhs)
{
itsAge=new int;
itsWeight=new int;
*itsAge=rhs.GetAge();
*itsWeight=*(rhs.itsWeight);
}

Cat::~Cat()
{
delete itsAge;
itsAge=0;
delete itsWeight;
itsWeight=0;
}

void main()
{
Cat cat;
cout<<cat.GetAge()<<endl;
cat.SetAge(89);
cout<<cat.GetAge()<<endl;
// cat boot(cat);
// cout<<boot.GetAge()<<endl;
cat.SetAge(98);
// cout<<cat.GetAge()<<endl;
// cout<<boot.GetAge()<<endl;
}

在你的类中对GetAge()声明处改为
int const GetAge() const
注意：在C++中在const对象和引用只能调用const函数
