Inheritance in C++

The file Animal.h contains an Animal class that stores the name and age of a generic animal. Besides the appropriate constructors, getters, and setters, it has a function called feed() which prints out the message "Some food, please!"

Dogs are one kind of animal, so we can extend the Animal class to produce a Dog class. Create a Dog class which inherits from the Animal class and change its constructor and destructor to print more appropriate messages and change the feed() function to print a message saying "Dog food, please!"

Your class should be stored in a file called Dog.h. Your solution will be tested with the file animals.cpp.

SAMPLE OUTPUT: Creating Generic Animal Creating Dog Snoopy is 4 years old. Dog food, please! Deleting Dog Deleting Generic Animal

animals.cpp

#include

#include "Dog.h"

using namespace std;

int main(int argc, const char * argv[])

{

Dog myDog = Dog("Snoopy", 4);

cout << myDog.getName() << " is " << myDog.getAge() << " years old. ";

myDog.feed();

return 0;

}
