write in c++ Define the 3 bolded functions for the Queue (circular array): class Queue { private: double array[10000]; int front, rear, numItems; public: Queue() {front = numItems = 0; rear = -1;} bool isEmpty(); bool isFull(); void enqueue(double d); int dequeue(); void dequeueMany(int n); //remove n values from the front void enqueueMany(double values[], int n); //add n values from the array}; Hints: void dequeueMany(int n) (hint 6 lines of code, no loops, if there are more than n elements in the queue, use math to re-compute front. Otherwise, make the queue empty. Don’t forget to update numItems. void enqueueMany(int values[], int n) (hint 3 lines of code, use a for loop, call another function, but make sure there’s enough room in the array first!! )

Following is the node class: class node { int v node *next: public: node(int x) {v=x; next3D03;} friend class list: }3; Implement the sequential list class below: class list { // circular list class // head position node *head; public: bool empty() { return !head;} list() {head-0;} ~list(); void add(int x); int get(); // empty list judgment / constructor // destructor, to be implemented // add to tail, to be implemented // get from head, to be implemented }3B
