//Animal.h

#include <string>
using namespace std;

class Animal
{
public:
   string favoriteFood;

   Animal();
   Animal(string n, double w, string ff);

   void setName(string n);
   void setWeight(int w);
   string getName();
   double getWeight();

private:
   string name;
   double weight;
   void incrementWeight(double inc);
};

//Animal.cpp

#include <string>
using namespace std;
#include "Animal.h"

Animal::Animal()
{
   name = "unknown_name";
   weight = 0.0;

}

Animal::Animal(string n, double w, string ff)
{

{
   weight = w;
}
