1. MaxBargain supermarkets has approached you to develop a billing software for their stores. The input is a list of products purchased by customers and you need to create a software to calculate the total bill with tax and discounts The format of input file "items.txt" is as follows Milk 1 3.75 20N Wine 2 10.99 0 Y Butter 1 4.99 5 N Flour 4 3.99 0 N Salmon 3 12.99 0 Y The input file is organized as, Product Name, Quantity purchased (number of units), price per unit, discount applicable and if the product is eligible for tax.
