Project 3
Aim: 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.
