Assuming the follow class template: template class Queue { private: // need to add a STL vector of T elements here. public: ~Queue (); T Dequeue (); void Enqueue (T new_element); }; 1) Add a private member to the Queue class above: a STL vector of T elements. 2) Provide definitions for the destructor ~Queue, Dequeue and Enqueue member functions (outside of class declaration): •Destructor: remove all elements from the vector. Don't worry about if T is a pointer to dynamic memory. • Public member functions • Dequeue: remove the first element in the vector and returns it as function's return type. If the vector is empty throw the library exception object. • Enqueue: add the object to the end of the vector. 3) Show code how to declare a Queue of Person objects. Enqueue three Person objects: "Jack", "Sunny" and "Matthew". Dequeue one person from the Queue. class Person { public: Person (); Person (string full_name);

2. Given the abstract data type (ADT) for static queue template in Queue.h below template class Queue { private: T *queueArray; int queueSize; int front; int rear; int numItems; public: Queue (int); Queue (const Queue &); -Queue (); void enqueue (T); void dequeue (T &); void splitqueue (T &); bool isEmpty() const; bool isFull() const; void clear (); } ; (a) Write the full definition for the public member method splitqueue that splits the contents of a queue into two different queues i.e. Odd_queue and Even_queue. This method print the appropriate queue based on user choice of 1 and 2 where 1 is for Odd queue and 2 for Even queue.

Given the following specification of a front operation for queue:ItemType Front Function: Returns a copy of the front item on the queue. Precondition: Queue is not empty. Postcondition: Queue is not changed. 1. Write this operation as client code, using operations from the QueType class. (Remember,the client code has no access to the private variables of the class). 2. Write this function as a new member function of the QueType class. help me with complete code

Goal: develop a class Queue, an ordered collection of objects that restricts insertions to the rear of the queue and removal from the front of the queue •The class Queue should support methods: • . Queue (): Constructor that initializes the queue to an empty queue enqueue (item): Add item to the end of the queue dequeue (): Remove and return the element at the front of the queue isEmpty(): Returns True if the queue is empty, False otherwise appts Queue () >>> appts.enqueue ('John') >>> appts.enqueue ('Annie') >>> appts.enqueue ('Sandy') >>> appts.dequeue () 'John' >>> appts.dequeue () 'Annie' >>> appts.dequeue () 'Sandy' >>> appts.isEmpty() True
