- BankCustomerQueueADT Implement in C++ a BankCustomer QueueADT that does the following: 1. gets the input about a customer (first name, last name, Bank Account Number, Money to be withdrawn/deposited, etc.) from the user (from the keyboard) 2. inserts (enqueues) the Customer as a record into the BankCustomerQueueADT (your Queue ADT must be able to have a maximum of 20 customer records) 3. removes (dequeues) the Customer record from the BankCustomerQueueADT 4. your BankCustomerQueueADT must also have the behavior of retrieving and displaying the Queue info on the screen after each event (either entry of a Bank Customer into the queue, OR leaving of the Bank customer from the queue). NOTE: Please make sure you debug, run, test and see the program working correctly before submitting. Make sure all the code statements are commented. Make sure your program is indented properly.Problem: Implement a part of functionality for the Netflix DVD queue. It's a service that allows a user to create a list of desired movies and then sends DVDs with movies on top (what we called head in our lectures) of this list to the subscriber one at a time. A subscriber should be able to create a list of desired movies and manipulate the order in a movie queue in their account. Your program will implement some of the desired functionality by storing the list of movie titles in a linked list. You are provided with the following files available in the "Downloadable files" section: MovieList.h contains a class declaration for the class that represents a list of movies. top refers to the head position of a list and bottom refers to the tail or end position of a list. Driver.cpp contains the main function you can use to test your implementation. *** NOTE: Please do not change any of the function names since our automated test script calls those functions.

The products they ship have some attributes, which are as follows: Product ID (Integer) [This is unique for every product] Product label (String) Manufacturer (String) All strings are of maximum length 100 and contain only alphanumeric characters. The products arrive one by one, and a common queue is maintained for all of them. Also, there is a fixed set of manufacturers the company has a tie-up with: Nike Adidas Reebok Puma Diadora You are to automate some repetitive tasks. The tasks are as follows: 1) Add a new product to the queue. 2) Deliver the next product of the queue and print the product information delivered. 3) Query how many products of a given manufacturer is currently present in the queue. 4) Query how many products of a given manufacturer has been shipped already. Initially, the product queue is empty. It is also guaranteed that when new products are…
- Write a JAVA program that will maintain a phone directory using a Linked-List. The program should be able to perform the following operations: 1) Add persons details (first name, last name, phone number, city, address, sex and email) to the phone directory, where phone numbers in the directory have to be unique. (Note: each person record will store in one node in the linked-list and insert each person to the last) 2) Delete any person details by a given phone number. 3) Update telephone number by providing person first name. 4) Display all details of persons from a phone directory. 5) Search telephone number based on person first name. (Note: use sequential search to find all telephones for the given first name) 6) Sort all persons in the phone directory ascending based on person first name. (Note: use bubble or selection sort to arrange the entire phone directory) Project Outputs The output has to display a menu of choices. Then the user can select which operation want to perform.…By using c++ programing language Take an integer n from the user as input and use a queue to print binary values of each integer from 1 to n. Here is how it can be done. Create an empty queue Enqueue the first binary number “1” to the queue. Now run a loop for generating and printing n binary numbers.o Dequeue and print the value.o Append “0” at the dequeued value and enqueue it.o Append “1” at the dequeued value and enqueue it Input, n=10; output: 1, 10, 11, 100, 101, 110, 111, 1000, 1001, 1010you are to design a printer queue that is responsible for handling the printing requests coming from different users. You have to take into consideration that users have different levels of priorities. Each user has an identification number and a password, in addition to printing priorities. One good idea is to design the queue using an array or pointers while preserving the first-in first-out concept of the queue. For every printing request received, the program should check the priorities of that request and whether it can be moved forward in the queue to be served by the printer prior to serving the other requests. Using the programming language of your choice (preferably C++), write the printer queue that would handle the user request. The program must allow for requests coming from different users or from one user. Note: I need a working C++ code for this problem, and i need priorities.
- C/C++ Using linked lists implement an amusement park reservation system. The system allows a person to make a reservation for a specific date. A person can change the reservation date or even cancel his booking anytime. The system puts all reservations in a queue. The park will allow only certain number of persons on any given day in order the reservation was made. For each day the system will print out persons allowed to visit the park. For sake of simplicity, dates are being confined to 15th to 30th. The system should ask the user to enter code for different operations. It reads all data from the datafile amusement.dat. The first integer on datafile indicates limit of persons allowed on any day. i)code 1: make reservation, system expects date followed by name (within 20 characters) and makes reservation. If number of bookings exceeds allowed number, then system prints SORRY, QUOTA OVER and moves over to read next code. ii)code 2: change date of reservation, system expects old date,…in c++ vs19 Using STL queues, implement an application that does the following: Use a queue in the implementation, read a text from the user. Check if the text is a palindrome (a set of letters or numbers that is the same whether read forward or backward) Print the result Application continues asking for a new word until the user wishes to quit example: User provides: "dom"Output: "It is not read same forward or backward. dom is not a palindrome."User provides: "alla"Output: "It is read same forward or backward. alla is a palindrome."10. Suppose you are given an implementation of a queue of integers. The operations that can be performed on the queue are: i. isEmpty (Q)– returns true if the queue is empty, false otherwise. ii. delete (Q) – deletes the element at the front of the queue and returns its value. iii. insert (Q, i) – inserts the integer i at the rear of the queue. Consider the following function: void QUE(queue Q) { int i ; if (!isEmpty(Q)) { i = delete(Q); QUE(Q); insert(Q, i); } } What operation is performed by the function QUE assuming the elements 1, 2, 3, 4 are in the queue ? %D Leaves the queue unchanged Empties the queue Q Reverse the order of the elements in queue Q Deletes the elements of the queue Q from the front and inserts it at the rear of the Queue Qkeeping the other elements in the same Ogen

(Note: use sequential search to find all telephones for the given first name) Sort all persons in the phone directory ascending based on person first name. (Note: use bubble or selection sort to arrange the entire phone directory)The specifications for the Unsorted List ADT state that the item to be deleted is in the list. Rewrite the specification for DeleteItem so that the list is unchanged if the item to be deleted is not in the list. Rewrite the specification for DeleteItem so that all copies of the item to be deleted are removed if they exist.write a C++ Program Your task is to develop a program for a hospital where they need help to calculate and maintainthe number of patients, their disease, and their allotted room numbers. You will use a SinglyLinkedList to store record of a patient such as patient name, patient CNIC, patient disease, admitdate and patient allotted room number.Suppose if a patient has been recovered then, you will need to delete his Node from the list (Useall methods of deletion Start, Middle, and End). The system will use a special function named asDichargePatient() that will take patient CNIC as parameter, remove node of the patient, and returnsuccess status of the operation.Whenever a new patient is arrived at the hospital for admitting in a room. The system will useanother function AdmitPatient() that takes patient’s information, checks the availability of a room(assume that hospital only have 20 rooms and only one patient per room is allowed).
