定义一个Dog 类，包含的age、weight等属性，以及对这些属性操作的方法。实现并测试这个类。

#include <iostream>

using namespace std;

class Dog
{
public:
    Dog (int Age0 = 0,int Weight0 = 5);
    ~Dog();
    int GetAge() { return Age1;}
    void SetAge (int age) { Age1 = age;}
    int GetWeight() { return Weight1;}
    void SetWeight (int weight) { Age1 = weight;}
    int Age1,Weight1;
};
Dog::Dog(int Age0, int Weight0)
{
    Age1 = Age0;
    Weight1 = Weight0;
}
Dog::~Dog() //destructor， takes no action
{
}
int main()
{
    Dog cindy(1,10);
    cout << "cindy 是一条狗 " ;
    cout <<"她"<< cindy.GetAge() << " 岁了";
    cout <<"有"<< cindy.GetWeight() << " 有公斤重\n";
    cindy.SetAge(7);
    cindy.SetWeight(20);
    cout << "现在 cindy 已经 " ;
    cout << cindy.GetAge() << " 岁了";
    cout <<"有"<< cindy.GetWeight() << " 公斤重.";
    return 0;
}
