Question 2

(Marks: 35)

You have to design your own Java console application about any valid problem that your

application must solve. Your solution can include solving a business problem, a new idea or even a

game. Your application must make use of concepts such as arrays, loops, inheritance, constructors

and information hiding. Output must be shown in the form of a report using the console.

In your solution, make use of as many concepts, and components dealt with in this course, but

pay special attention to the following learning units:

Learning Unit 1: Advanced arrays.

Learning Unit 2: Introduction to inheritance.

1. In your solution, you must create a class called Products, which will contain all your working
methods.
2. This class will, as a minimum, contain the following methods, but you are encouraged to
add more methods:
• SearchProduct();
• SaveProduct();
• UpdateProduct();
• DeleteProduct();
• DisplayMenu();
• CaptureProduct();
• ExitApplication();
3. Finally, create a main class to run your application

Write a C++ program that tells the size of linked list and counts the elements present in the list and displays the data

Note:
no global declarations
Make class or struct

Write C++ program that that contain functions
1) A function to Delete the last node of doubly Linked List
2)A function at deletes the 2nd-last node of the doubly Linked List
3)A function that displays the Linked lists
Call the functions in main

NOTE:
1) make class or struct
2)No global declarations

1. In your solution, you must create a class called Products, which will contain all your working
methods.
2. This class will, as a minimum, contain the following methods, but you are encouraged to

Towers of Hanoi: One of the most popular puzzle is called Towers of Hanoi . It consists
of three rods (or towers) with a specific number of disks with different sizes in one
rod, arranged in ascending order (from the top) from smallest to largest. The goal
is to move the stack of disks from the starting rod to any of the other two. But there
are certain rules to be followed. Firstly, place randomly disks in the towers
The rules of the puzzle are:
• Only one disk may be moved at a time.
• Each move consists of taking the upper disk from one of the rods and sliding it
onto another rod, on top of the other disks that may already be present on that
rod.
• No disk may be placed on top of a smaller disk.

Write C++ code for the above problem
