This project outlines the design of a car rental application, targeting modern users seeking convenient car rental services for travel or daily commutes. The application allows users to register, manage profiles, and book cars, with functionalities including location selection, car options (with or without a driver), and price calculation. The design incorporates use case diagrams, storyboards illustrating user registration, profile editing, and booking processes, and sample input/output scenarios for testing key functionalities. The failure case is also considered to improve the application. The goal is to provide a user-friendly interface with essential features for efficient car rentals.
