Program Description Answer
A queue is a collection of items which are accessed first-in-first-out fashion. For example, the order of cars enters and leaves in a toll booth. The cars will follow first in first out order.
Hence, the correct answer is option “B”.

Students have asked these similar questions
Write a program that creates a linked list to represent details of students.
• SID (for Student ID)
• Name
• Address
• Age
• Gender
Your program must also display a menu to perform the following tasks:
• Create a linked list.
The method to create a linked list makes use of the method insertFirst() or insertLast() or insertOrdered()
• Insert new nodes to the linked list.
• Search for details pertaining to a particular student.
• Delete details of a particular student.
• Find number of nodes in the linked list.
• Display information pertaining to all students.
The menu options should be as follows:
1. Create linked list
2. Add new student
3. Search for a student
4. Delete a student
5. Find number of students
6. Print student details
7. Exit
The front method of the array based queue Select one: a. Change the front but the rear is not changed b. Change the rear but the front is not changed c. Change the front and the rear d. Not change the front and the rear
Queue is referred to be as First-In-First-Out (FIFO) list. True or False

- You need to implement a class named "Queue" that simulates a basic queue data structure. The class should have the following methods: Enqueue(int value) - adds a new element to the end of the queue Dequeue() - removes the element from the front of the queue and returns it Peek() - returns the element from the front of the queue without removing it Count() - returns the number of elements in the queue The class should also have a property named "IsEmpty" that returns a boolean indicating whether the queue is empty or not. Constraints: The queue should be implemented using an array and the array should automatically resize when needed. All methods and properties should have a time complexity of O(1) You can write the program in C# and use the test cases to check if your implementation is correct. An example of how the class should be used: Queue myQueue = new Queue(); myQueue.Enqueue(1); myQueue.Enqueue(2); myQueue.Enqueue(3); Console.WriteLine(myQueue.Peek()); // 1…arrow_forward9 T OR F Depending on the circumstances, the dequeue method of our LinkedQueue class sometimes throws the QueueUnderflowException.arrow_forwardYou can access any element on a queue.
