Build two classes: Mammal and Dog, where Dog will be derived from Mammal. You are given the code for the Mammal class and are expected to build a Dog class (using Dog.h and Dog.cpp) in similar fashion, except that Dog should be derived from Mammal:

Mammal.h:

#include using namespace std;

class Mammal {

public: Mammal();

~Mammal(); virtual void Move() const; virtual void Speak() const;

protected: int move;

};

Mammal.cpp:

#include "Mammal.h"

Mammal::Mammal() : move(1) {

cout << "Mammal constructor..." << endl; }

Mammal::~Mammal() {

cout << "Mammal destructor..." << endl; }

void Mammal::Move() const {

cout << "Mammal moves " << move << " step!" << endl; }

void Mammal::Speak() const {

cout << "What does a mammal speak? Mammilian!" << endl; }
