Operator Overloading; Inheritance and Abstract data types

Advanced inheritance, abstract data types, and templates

Here's a class hierarchy that will be used in several of the problems (Instead of writing a separate answer for each question, just the final rite answer after you've made all the modifications required by the problems struct animal float eight struct pet public animal string name; struct dog public pet bool can fetch false struct cat public pet int lives left 9 (Remember that struct is just a version of class which defaults to public rather than private' access.) 1) Add a virtual method is tame to the hierarchy which should return true for all pet's but false for animals in general 2) Add a virtual method fetch to pet By default this does nothing, but for dogs it should check can fetch and print a message if the dog actually can fetch 3) Add a pure virtual method speak to pet which should print a message typical of a particular kind of pet. E. g dogs bark while cats meow. d the existing virtual methods 3) Ad d a subclass t for rabbit d exten o pet an to it rite a class pet owner which HAS-A ector of p et pointers Give this 4) Wi class a method pets speak hich just has all the owned pets do their speak ing E.g., for a pet owner who had a cat and a dog, running the pets speak ethod might print Meow Woof 5) On the pet owner class overload the operator operator to take an unsigned in i' and return the i-th pet owned by that owner. (That is, this acts like at on the vector of pets. YOUR ANSWER HERE suppose we added a class animal owner which contained a vector o is this class related to pet owner? nimal pointers Conceptually how Can an animal owner do everything a pet owner can making animal owner a subtype of pet owner)? Or is it the other way around, that pet owner can do everything an animal owner class so that pet owner is a subtype of animal owner Or is it some other kind of relationship YOUR ANSWER HERE

Explanation / Answer

As per the Chegg policy we can answer upto 4 questions. Please don't mind.

Here i have answered 5 questions.

#include<iostream>
using namespace std;

struct animal{
float weight;
virtual bool is_tame(void){ return false;}
};

struct pet:public animal{
string name;
bool can_fetch;
virtual bool is_tame(void){ return true;}
virtual void fetch(void){
   if(can_fetch)
       cout<<"The "<<name<<" can fetch"<<endl;
   else
       cout<<"The "<<name<<" can't fetch"<<endl;
}
virtual void speak(void) =0;
};

struct dog:public pet{
bool can_fetch;
virtual void speak(void){
   cout<<"Dogs bark"<<endl;
}

};

struct cat:public pet{
int lives_left;
virtual void speak(void){
   cout<<"Cat meow"<<endl;
}
};

struct rabbit:public pet{
   virtual void speak(void){
       cout<<"Rabbits snore"<<endl;
   }
};

class pet_owner{

pet **p;
int n;//number of pets

   void addPets(void)
   {
      int t=0;
       for(int i=0;i<n;i++)
       {
           cout<<"1.Dog"<<endl;
           cout<<"2.Cat"<<endl;
           cout<<"3.Rabbit"<<endl;
           cin>>t;
           switch(t){
           case 1:
               p[i]=new dog;
               break;
           case 2:
               p[i]=new cat;
               break;
           case 3:
               p[i]=new rabbit;
               break;
           }
       }
   }
  
public:
   pet_owner(int n){
       this->n=n;
       p= new pet*[n];

       addPets();
   }

void pet_speaks(){
   for(int i=0;i<n;i++)
       p[i]->speak();
}

pet * operator [](int i)
{
   return p[i];
}

};

int main(void)
{
   pet_owner pt(2);
   pt.pet_speaks();

   pet *p=pt[1];

   p->speak();


}
