Assignment
Write a program in Pyton programming language, which allows the user to input an integer value for a variable named upperLimit. Based on the input value, the program should perform the following tasks:
• Check whether the value entered by the user falls within the range from 1 to 100. (1 and 100 included in the given range.)
• Calculate and display the sum of all numbers within the range (1 to upperLimit).
• Calculate and display the average of all numbers within the range (1 to upperLimit).
• Calculate and display the total number of numbers within the range (1 to upperLimit).

Objectives:
To enable students to write, execute a program in Python. Moreover to familiarize students with the concepts of:
• Classes and objects
• Constructor
• Object declaration
• Methods/functions calling
Assignment Submission Instructions
You have to submit only.py file on the Assignments interface of CS441 at VULMS. Assignment submitted in any other format will not be accepted and will be graded zero marks.
Lectures Covered: This assignment covers Weeks # 03 - 05
Deadline
Your assignment must be uploaded/submitted on or before 18/06/2020.
Question statement:
Write a Python program that will create a class named Employee.
This class will have 4 data members:
ID
Name
Address
Designation
The Employee class will have the following setter functions:
setID(), which takes a single parameter of appropriate data type
setName (), which takes a single parameter of appropriate data type
setAddress(), which takes a single parameter of appropriate data type
setDesignation(), which takes a single parameter of appropriate data type
The Employee class will have the following getter functions:
getID()
getName()
getAddress()
getDesignation()
You are required to write a default constructor for this class.
In the default constructor, you will initialize all the data members with the its default values. The message “Default constructor called” should be displayed whenever an object is created with the default constructor.
Now, create an object by using the default constructor and display the values of data members through calling getters functions.
Then set the values of the data members by calling the setters functions and then display its values by calling getters functions.

Question statement:
Write a Python program that will create a class named Product.
This class will have 4 data members:
Name
Brand
Price
Quantity
The Product class will have the following setter functions:
setName (), which takes a single parameter
setBrand(), which takes a single parameter
setPrice(), which takes a single parameter
setQuantity(), which takes a single parameter
The Product class will have the following getter functions:
getName()
getBrand()
getPrice()
getQuantity()
You are required to write a parameterized constructor for this class.
In parameterized constructor, you will initialize all the data members with the values passed to it as an arguments. The message “Parameterized constructor called” should be displayed whenever an object is created with the parameterized constructor.
Now, create an object by using the parameterized constructor and display the values of data members through calling getters functions.
Then set the values of the data members by calling the setters functions and then display its values by calling getters functions.

• Calculate and display the sum of all even numbers within the given range (0 to upperLimit).
• Calculate and display the sum of all odd numbers within the given range (0 to upperLimit).
• Display the total number of even and odd numbers within the given range (0 to upperLimit).
