Explanation / Answer

Hi, Please find my implementation.

Please let me know in case of any issue.

#include <iostream>
#include <cstdlib>
using namespace std;

class Pet
{
protected:
string type;
string name;
public:
Pet(const string& arg1, const string& arg2);
virtual void describe() const;
virtual string speak() const = 0;
};

class Dog : public Pet
{
public:
Dog(const string& arg1, const string& arg2):Pet(arg1, arg2){

}
void describe() const{
cout<<"I am an excellent dog and you may refer to me as "<<name<<endl;
}

string speak() const{
return type;
}

};

class Cat : public Pet
{
public:
Cat(const string& arg1, const string& arg2):Pet(arg1, arg2){

}

void describe() const{
cout<<"I am an excellent dog and you may refer to me as "<<name<<endl;
}

string speak() const{
return type;
}
};

ostream& operator<<(ostream& out, const Pet& p)
{
p.describe();
out << "I say " << p.speak();
return out;
}

int main()
{
Dog fido("dog","Fido");
Cat garfield("cat","Garfield");
Pet* ptr = &fido;
cout << *ptr << endl;
