Given this c++ linked list header file called "llist.h",  implement the function, T deleteAt(int index); ,  please       Llist.h: #ifndef LLIST_H#define LLIST_H#include <string>#include <iostream> //a list node is defined here as a struct Node for nowtemplate <typename T>struct Node{  T elem;         // elem is the element stored  Node<T> *next;  // next is the pointer to the next node};//--------------------------------------------------------- template<typename T>class llist {private:  Node<T>* front;      // pointer to the front node  Node<T>* rear;       // pointer to the rear node  int count;           // counter for the number of nodes public: T deleteAt(int index);

The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.

How is an array stored in main memory? How is a linked list stored in main memory? What are their comparative advantages and disadvantages? Give examples of data that would be best stored as an array and as a linked list.
