You are given the following segment of code. All the following C++ questions are based on this code.

class Owner { public: int iPhone; string sEmail; Owner(int phone, string email) { // constructor iPhone = phone; sEmail = email; } };

class Pet { public: string sName; Owner *pOwner; Pet(string name, int phone, string email) { // 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) . . . // write the constructor

};

class PetNode { public: PetNode *pNext; Pet *pNode; PetNode() { pNode = NULL; pNext = NULL; }; } *head = NULL; // head is the global pointer to the PetNode linked list

void insertPet(); void insertCat(); //...

void main(void) { Pet* p; Cat* c; PetNode* pn; // input the data here insertPet(); insertCat(); // ... }

The following diagrams show the relationships among the classes and an example of the linked list constructed using the classes.

1. Write the insertCat function to insert a Cat object into the linked list (whose nodes are of PetNode type). The start pointer of the linked list is head pointer. Insert the new node at the end of the linked list (as the last node). You do not have to write "Get" and "Set" functions to access the members of any class. You can directly access them. You can assume that the required input data are entered in the main program before calling the insertCat method. [7 points]

void insertCat(char *name, int phone, char *email, string breed, int age)
