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!! )
ALL TRUE OR FALSE QUESTIONS 1. The text's array-based queue implementations use the fixed-front approach. 2. The enqueue and dequeue queue operations are inverses of each other. Therefore, performing an enqueue followed by a dequeue is always equivalent to performing a dequeue followed by an enqueue. 3. It is possible to implement an unbounded queue using an array-based approach. 4. Our QueueInterface defines two constructors. 5. The isEmpty operation as defined for the text's Queue ADT might throw the QueueUnderflowException. 6. A "dequeue" allows an application to peek at the front of rear values of a queue. 7. A java interface can inherit from at most one other interface. 8. The main thread of a Java program cannot generate additional threads. 9. Code sequences in concurrent programs never interfere with each other.
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.
in c++ Write a function that takes a queue with 20 integer values and deletes the elements thatare between 15 and 20. In other words, only the elements less than 15 or greater than 20remain in the queue. This means that you need to have an auxiliary queue to store theelements between 15 and 20 and restore them back to the original queue.
class Queue { private static int front, rear, capacity; private static int queue[]; Queue(int c) { front = rear = 0; capacity = c; queue = new int[capacity]; } static void queueEnqueue(int data) { if (capacity == rear) { System.out.printf("\nQueue is full\n"); return; } else { queue[rear] = data; rear++; } return; } static void queueDequeue() { if (front == rear) { System.out.printf("\nQueue is empty\n"); return; } else { for (int i = 0; i < rear - 1; i++) { queue[i] = queue[i + 1]; } if (rear < capacity) queue[rear] = 0; rear--; } return; } static void queueDisplay() { int i; if (front == rear) { System.out.printf("\nQueue is Empty\n"); return; } for (i = front; i < rear; i++) { System.out.printf(" %d <-- ", queue[i]); } return; } static void queueFront() { if (front == rear) { System.out.printf("\nQueue is Empty\n"); return; } System.out.printf("\nFront Element is: %d", queue[front]);…
