Jun 1, 2026Summary for 2026-06: Delivered two key features in the ia2407-114/114-1-junior-college-C-plus-plus-program repository. 1) Flight Object Type Hierarchy and Polymorphism: introduced a base class flight_object with derived classes for airliners, battleplanes, and bombplanes, demonstrating virtual functions and multiple inheritance to handle aircraft-specific attributes. 2) Cinema Management System with Binary File I/O: implemented a cinema management system with binary file I/O, including input, save to binary file, and retrieval by index, using a struct-based data model and a manager class to encapsulate file operations. No major bugs fixed in this period. Overall, these efforts establish a scalable OO design for aircraft types and robust binary persistence for cinema data, enabling faster feature delivery and improved maintainability. Technologies and skills demonstrated include C++ OO design (base/derived classes, virtual functions, multiple inheritance), binary file I/O, struct-based data modeling, and the manager class pattern.
