A C++ fishing regulation management system that lets anglers log catches and validates them against species-specific keeping rules. Built to demonstrate practical application of object-oriented design patterns.

Design Patterns

• Facade — CommunicationFacade provides a unified interface to the creature and angler subsystems, hiding internal coordination from the client.
• Factory — SeaCreatureFactory and SeaCheckerFactory abstract the construction of concrete creature and checker types.
• Builder — SeaCreatureBuilder constructs SeaCreature objects step-by-step with chained setters.
• Mediator — AnglerEngine and SeaPlusPlusEngine coordinate interactions between subsystem components without coupling them directly.
