#include using namespace std;

class Animal { public: Animal(string n): name(n) {} virtual ~Animal() {} virtual void makeNoise() = 0; protected: string name; };

class Dog: public Animal { public: Dog(string n): Animal(n) {} void makeNoise() override { cout << name << " says woof!" << endl; } };

class Cat: public Animal { public: Cat(string n): Animal(n) {} void makeNoise() override { cout << name << " says meow!" << endl; } };

int main () { Dog myDog("Lassie"); myDog.makeNoise(); Cat myCat("Bella"); myCat.makeNoise(); return 0; }

-------------------------------------------------------

in main () add an array of four animals, two dogs and two cats. then use a for loop to call the makeNoise () function for each array element.
