1. 定义一个哺乳动物类 Mammal,并从中派生出一个狗类 Dog,下面给出 Mammal 类得定义,要求:（1）添加 Dog 类得颜色数据成员,访问属性为私有,通过 SetColor 与 GetColor 成员函数来对颜色进行设置与猎取。（2）分别为基类与派生类添加相应得构造函数(有参、无参)与析构函数,并进行测试。class Mammal{protected:int itsAge;int itsWeight;public:int GetAge{return itsAge;}void SetAge(int age) {itsAge=age;}int GetWeight { return itsWeight;}void SetWeight(int weight) {itsWeight= weight;} };class Dog : public Mammal{//定义 Dog 类得数据成员与成员函数};改:#include #include using namespace std;class Mammal{protected:int itsAge;int itsWeight;public:Mammal;~Mammal;int GetAge{return itsAge;}void SetAge(int age) {itsAge=age;}int GetWeight { return itsWeight;}void SetWeight(int weight) {itsWeight= weight;} };class Dog : public Mammal{protected:char itscolor[20];public:Dog;void Setcolor(char *color) {strcpy(itscolor,color);} void getcolor{cout<<"狗得颜色"<>age1;SetAge(age1);cout<<"请输入动物得体重:"<>weight1;SetWeight(weight1);}Mammal::~Mammal{cout<<"Destructor called、"<>color;Setcolor(color);cout<<"狗得颜色"<
