# Question 3:
# Define a class named Product with the following specifications:
# Data members:
# 1-product_id – A string to store product.
# 2-product_name - A string to store the name of the product.
# 3-product_purchase_price – A decimal to store the cost price of the product.
# 4-product_sale_price – A decimal to store Sale Price Margin - A decimal to be calculated as (product_sale_price - product_purchase_price)
# 5-Remarks - To store "Profit" if Margin is positive else "Loss" if Margin is negative.
# Methods :
# A constructor to intialize all the data members with valid default values.
# A method set_remarks() that assigns Margin as (product_sale_price - product_purchase_price) and sets Remarks as mentioned below :
# Margin             Remarks
# < 0 (negative)     Loss
# > 0 (positive)     Profit
# A method set_details() to accept values for product_id, product_name, product_purchase_price, product_sale_price and invokes SetRemarks() method.
# A method get_details() that displays all the data members.
