My teacher feedback was "this exercise does not have functionality to list (print), delete or update hardware items". Below is my code. How can I fix it? thank you

You are the owner of a hardware store and need tokeep an inventory that can tell you what different tools you have,how many of each you have on hand and the cost of each one.Write a program that initializes the random accessfile hardware.dat to 100 empty records, lets youinput the data concerning each tool., enables you to list allyour tools, lets you delete a record for a tool that you no longerhave and lets you update any information in the file. The toolidentification number should be the record number. Use thefollowing information to start your file.

Record #	Tool name	Quantity	Cost
3	Electricsander	18	35.99
19	Hammer	128	10.00
26	Jigsaw	16	14.25
39	Lawnmower	10	79.50
56	Powersaw	8	89.99
76	Screwdriver	236	4.99
81	Sledgehammer	32	19.75
88	Wrench	65	6.48
