Language used: Python Programming

Program:

#Entering the records accepted from the user, into a binary file

filee = open("item.dat","ab")

items=[]

no_of_items=int(input())

for i in range(no_of_items):

   Item_No = int(input())

   Item_Name = input()

   Qty = int(input())

   Price = float(input())

   items.append([Item_No, Item_Name, Qty, Price])

pickle.dump(items, filee)

filee.close()

#Reading the data from the binary file

f = open("item.dat","rb")

data= pickle.load(f)

for record in data:

   print("Item No: ",record[0])

   print("Item Name: ",record[1])

   print("Quantity: ",record[2])

   print("Price per item: ",record[3])
