confusing about the additional operations, how to design it ?

[assasi123]

You are required to write a program for a Used Car Dealer company. In the system you need
to maintain the cars’ inventory and details. Each car in the company contains the following
details:
• Car Registration Number
• Car Make or Brand
• Car Model
• Car Colour (eg. Silver, Black , Red)
• Year of manufacturing (The year the car was manufacture)
• Engine Capacity (in cc)
• Transmission (manual or automatic)
• Cost of the car (RM)
The Car Registration Number is in the format of AAA1234 or AA1234A or A1234A which is
accordance to the Malaysia car registration format. The A alphabet is in accordance to the
registration number for respective in Malaysia. (eg. AEW9829 or W1212Y or MCD1177).
Note the A and the 1234 total count in the registration number can be less than 3 like AT9829
or BHY280.
The Car Make is for the identifying the manufacturer of the car like Honda, Toyota,
Proton..etc.
The Car Model is to represent the Manufacturers’ respective model like Honda City, Honda Civic, Honda Accord, Toyota Vios, Toyota Camry … etc.
You are required to create menu and operations for:
1) Create a new Car account
2) Edit existing Car account details
3) Remove a car account from the system
4) Search for cars in the system (based on Car Make, Model, Year of manufacturing or Price)
5) Check total inventory in the system

**propose two additional
operations that can be performed by the system.
