1.1 A Retail has name, a List containing Items available in the stock and another List containing sold items. [2] 1.2 A Retail have functionality to view available stock, that prints Class name of item, name of Item, size of item and total number of items that have same name, and size. [5] EXAMPLE
ClassName Item name Size Drink coke 1 Drink coke 2
Total
10; // this show that in the list there are 10 coke that are size of 1
5; // this show that in the list there are 5 coke that are size 2 Sizes in drinks means litres.
Hint: Items are the same if their class name, item name and size are the same.
