Project 3
Build an object-oriented library which can be used to track automobile maintenance. There can be different car types such as petrol, diesel, gas, electric etc., This library should be able to support at least three of the car types.
Maintenance tasks include activities like oil change or replace oil filter, replace air filter, replace fuel filter, tire rotations, infotainment system debug, replace spark plugs, replace the cabin or a/c filter, check the level and refill clutch fluid or brake fluid, examine belts, wipers, hoses, check the tire conditions, check the charging systems and battery.
Every vehicle should have the following details:
-
Make
-
Model
-
Year
-
Odometer reading
The library interfaces or the API’s (Application Program Interface) should be capable of adding, updating, listing and removing the entries at runtime.

OUTPUT
The menu appears and user can enter the requrired function.Suppose if user selects Add Vehicle,
the menu asks to enter fuel type and then the vehicle details .After entering it returns to main menu.
If user selects List vehicle,then the entered vehicle details in the inventory will appear.
If the user selects Update vehicle,the menu shows entered vehicles and asks to enter the no of corresponding vehicle to update,then it asks to enter the modified vehicle details.
If the user selects Remove vehicle,the menu shows entered vehicles and asks to enter the no of corresponding vehicle to remove.
If the user selects Tire Rotation,the menu shows entered vehicles and asks to enter the no of corresponding vehicle to check whether the entered vehicle requires the tire rotation.
If the user selects Oil Change,the menu shows entered vehicles and asks to enter the no of corresponding vehicle to check whether the entered vehicle requires Oil change.
If the user selects Recharge,the menu shows entered vehicles and asks to enter the no of corresponding vehicle to check whether the entered vehicle requires Recharge
User enters the Tire Rotation(to check whether tire rotation is needed)
User enters Oil chage (to check whether oil change is needed)
User enters Recharge (to check whether Recharge is needed)
