Requirements

Needs PArkinglot System, where both driver and PArking atendee can access. I t needs to be able to query availability. IF the spot is avlible the driver should be able to request a parking spot, if not it should be void. Once the parking request goes through the Parking atendee should be able to check availability and assign the parking spot once the parking fee is payed. This fee is processed through the system when the parking spot is assigned, the fee will be calculated and returned back to the driver and the parking attendent.




Define Core Objects

Driver, PArking Attendee, PArking lot System, Fee calculator, Avalibility, Parking Request, PArking spot Assignment





Analyze Relationships

Driver and PArking Attendee interact with the PArking SYstem wich then can access the backend to calculate the fee based on the requested spot, check avlibility and set the spot to assigned or iunassigned.




Establish Hierarchy

Design inheritance trees where applicable to promote code reuse and polymorphism. This step involves identifying common attributes and behaviors that can be abstracted into parent classes...

Define Class Members (write code)

Attributes: For each class, define the attributes (data) it will hold...

Methods: Define the methods (functions) that operate on the attributes. Ensure they align with the object's responsibilities and adhere to the principle of encapsulation.
