Add menu options to retrieve a car record

by a car by Id or Model name a user should be able to search by ID or by item name create only one submenu option for searching the search should not be case sensitive (for example, a user may enter sTRolleR or STROLLER); store items in all lower/upper case to expedite the search write one search function that can search by ID and name and goes through the array of structs/objects only once allow partial search; must return all matching items (for example, a user can enter "roll" to search for a "stroller"; return "rolls", "stroller"); see C++ find() function show the entire record if found or an appropriate message if not by a price range user should be able to enter the target price and the range; for example target price: 5000 range %: 20 20% of 5000 is 1000, display all valid car records with a price at least $4000 (5000-1000) and no more than $6000 (5000+20%)

both IDs below should be valid but 12ABmP34Z is not found when testing code

12ABMP34Z Fusion_5 20 17000.00 12ABmP34Z Fusion_5 20 17000.00
