Differentiate between a class and object with some example. Also prepare a list of objects that you would expect each of the following systems to handle : (1) a program for laying out a news paper, (2) a catalog store order entry system.

S. No.	Aspect	Class	Object
1.	Definition	Blueprint or template from which objects are created	Instance of a class
2.	Grouping	Represents a group of similar objects	A real-world entity with specific attributes
3.	Nature	Logical entity	Physical entity
4.	Declaration	Declared using the class keyword	Created through the new keyword
5.	Instances	Declared once	Created many times as per requirement
6.	Memory Allocation	Does not allocate memory when created	Allocates memory when created

Examples:

1. Program for laying out a newspaper:
   • Classes: Page, Column, Line, Headline, Paragraph
   • Objects:
     • Page1, Page2, Page3 (instances of the Page class)
     • Column1, Column2 (instances of the Column class)
     • Headline1, Headline2 (instances of the Headline class)
2. Catalog store order entry system:
   • Classes: Customer, Order, Store, Item
   • Objects:
     • Customer1, Customer2 (instances of the Customer class)
     • Order1, Order2 (instances of the Order class)
     • Store1, Store2 (instances of the Store class)
     • Item1, Item2 (instances of the Item class)

In the newspaper layout program, each class represents a distinct component of the layout, and objects are instances of these classes representing specific elements on a page.

In the catalog store order entry system, the classes represent entities involved in the ordering process, and objects are instances representing specific customers, orders, stores, and items in the system.
