Define a Pet class that stores the pet's name, age, and weight. Add appropriate constructors, accessor, and mutator functions. Also define a function named getLifespan that returns a string with the value "unknown lifespan." Encapsulate this "Pet" class in its files of interface (pet.h) and implementation (pet.cpp). Next, define a Dog class in separate files (dog.h and dog.cpp) that is derived from Pet. The Dog class should have a private member variable named breed that stores the breed of the dog. Add mutator and accessor functions for the breed variable and appropriate constructors. Redefine the getLifespan function to return "Approximately 7 years" if the dog's weight is over 100 pounds and "Approximately 13 years" if the dog's weight is under 100 pounds. Define another Rock class in separate files (rock.h and rock.cpp) that is derived from Pet again. Redefine the getLifespan function to return "Thousands of years". Finally, write a test program that creates instances of pet rocks and pet dogs to exercise the inherited and redefined functions. < Remark > Separate compilation of all classes (Pet, Dog and Rock) is required, which means you will need to upload 8 files (pet.h, pet.cpp, dog.h, dog.cpp, rock.h, rock.cpp, main.cpp, makefile) in the folder named "5" in the directory. The description regarding functionalities, data input/output of each class should be included by comments in the interface file of each class. The lack of clear description in comments will deduct your points.
