# Question 2:
# Define a class named ItemInfo with the following description:
#
# item_code(Item Code), item(item name), price(Price of each item), qty(quantity in stock),
# discount(Discount percentage on the item), net_price(Price after discount)
#
# Methods :
# A member method calculate_discount() to calculate discount as per the following rules:
# If qty <= 10 —> discount is 0
# If qty (11 to 20 inclusive) —> discount is 15
# If qty >= 20 —> discount is 20
# A constructor init method to assign the initial values for item_code to 0 and price, qty, net_price and discount to null
# A function called buy() to allow user to enter values for item_code, item, price, qty.
# Then call function calculate_discount() to calculate the discount and net_price(price * qty - discount).
# A function show_all() or similar name to allow user to view the content of all the data members.
