大佬们能不能帮忙看一下这个程序哪里还不对？？

题目
补充程序 ：

1、实现Mammal类的方法

2、由Mammal类派生出Dog类，在Dog类中增加itsColor成员(COLOR类型)

3、Dog类中增加以下方法：

constructors: Dog()、Dog(int age)、Dog(int age, int weight)、Dog(int age, COLOR color)、 Dog(int age, int weight, COLOR color)、~Dog()

accessors: GetColor()、SetColor()

Other methods: WagTail()、BegForFood() ，并实现以上这些方法 。

提示：类似Speak()、WagTail()这些动作，函数体可以是输出一句话。比如：Mammal is spaeking... , The Dog is Wagging its tail...

4、补充主函数的问号部分，并运行程序，检查输出是否合理。

我的程序

#include<iostream>
using namespace std;
enum COLOR{ WHITE, RED, BROWN, BLACK, KHAKI };

class Mammal
{
public:
int n,m;
//constructors
Mammal();
Mammal(int age);
~Mammal();

//accessors
int GetAge() const
{
return n;
}
void SetAge(int n)
{
this->itsAge =n;
}
int GetWeight() const
{
return m;
}
void SetWeight(int m)
{
this->itsWeight=m;
}

//Other methods
void Speak() const;
void Sleep() const;
protected:
int itsAge;
int itsWeight;

};
void Mammal::Speak()const
{
cout<<"Mammal is speaking..."<<endl;
}
class Dog:public Mammal
{
public:
Dog();
Dog(int age);
Dog(int age, int weight);
Dog(int age, COLOR color)
{
SetAge(n);
this->itsAge =age;
}
Dog(int age, int weight, COLOR color)
{
this->itsWeight =weight;
}
~Dog();
void WagTail()
{
cout<<"The dog is wagging its tail..."<<endl;
}
private:
COLOR itsColor;
};
int main()
{
Dog Fido;
Dog Rover(5);
Dog Buster(6, 8);
Dog Yorkie(3, RED);
Dog Dobbie(4, 20, KHAKI);
Fido.Speak();
Rover.WagTail();
cout << "Yorkie is " <<Yorkie.GetAge ()<< " years old." << endl;
cout << "Dobbie weighs " <<Dobbie.GetWeight() << " pounds." << endl;
return 0;
}

预期结果谁什么，输出结果是什么

对不起，刚看见 Mammal is speaking... The dog is wagging its tail... Yorkie is 3 years old. Dobbie weighs 20 pounds.

你把原题目发我吧，这个问号的地方是你自己补充？
