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.

In above program first step is to add vehicle as shown in the above image
next step add another vehicle
Then check for tire rotation as shown in the above image
check for the oil change required
we can aslo check for the battery cahnge
