class SimpleCat
{
public:
    SimpleCat();
    ~SimpleCat();
    void SetAge(int age){*itsAge=age;}
    int GetAge(){return *itsAge;}

    void SetWeight(int weight){*itsWeight=weight;}
    int GetWeight(){return *itsWeight;}

private:
    int *itsAge=0;//类里的数据成员的初始化或赋值得在构造函数里完成，int *itsAge;
    int *itsWeight;
};

SimpleCat::SimpleCat()//改写成SimpleCat::SimpleCat():itsAge(0)这个就是对指针进行初始化
{
//或者你在这儿写itsAge = 0;
    itsAge=new int(2);
    itsWeight=new int(20);
}

SimpleCat::~SimpleCat()
{
    delete itsAge;
    delete itsWeight;
}
