Wei Yi developed a new Pet class for the ia2407-114/114-1-junior-college-C-plus-plus-program repository, focusing on foundational object-oriented programming concepts in C++. The class encapsulated pet attributes such as name and age, and included a display method to present this information clearly to users. By implementing a destructor, Wei Yi ensured proper resource management and cleanup, adhering to RAII principles. This work established a maintainable structure for future pet-management features and potential UI integration. The project demonstrated Wei Yi’s proficiency in C++ and object-oriented design, delivering a reliable, extensible component that aligns with core educational objectives in software engineering.
