Question

You are given the following segment of code. All the following C++ questions are based on this code class Ownerf public int Phone, string sEmail; Owner(int phone, string email)f II constructor iPhone phone; sEmail email; class Pet public string sName; Owner "pOwner; Pet(string name, int phone, string email) f II constructor sName -name; pOwner new Owner(phone, email); class Cat public Pet public string cBreed; int iAge; Cat(string name, int phone, string email, string breed, int age)... I/ write the constructor class PetNode public PetNode pNext Pet PetNode() { pNode = NULL; pNext = NULL; }; pNode; )'head = NULL; // head is the global pointer to the PetNode linked list void insertPet); void insertCat) Il void main(void) Pet* p; Cat* c; PetNode* pn; // input the data here insertPet(...); insertCat(...);

Explanation / Answer

1)

Pet *objpet; //this line is before the initialization of Cat constructor
Cat(string name,int phone,string email,string breed,int age)
{
   cBreed=breed;
   iAge=age;
   objpet=new Pet(name,phone,email);
}

2)

A destructor has the same name as the class name, prefixed with a tilde (~) and it can neither return a value nor can it take any parameters

to create a destructor for the class Cat we just have to write

~Cat();

3)

void insertAtEnd(struct node* head, int num){

    /* Input validation */

    if (head == NULL) {

       printf("Error : Invalid node pointer !!! ");      

       return;

    }

    /* creates a new node */

    struct node* newNode =(struct node*) malloc(sizeof(struct node));

    newNode->data = num;

    newNode->next = NULL;

    /* Traverse from head to last node */

    while(head->next != NULL)

       head = head->next;

     

    /* Insert newNode after Tail node */

    head->next = newNode;

}

Here I have shown that how can we add a node to the end of the linked list

If you have any query do comment below and if you like my solution please give a thumbs up!

Thanks :)
