Worked on the GamesmanClassic repository to enhance move display and input handling for a game development project using C. Focused on refactoring the mdorvoncag.c module, the developer improved the logic in functions responsible for displaying valid moves and processing player input, including handling special cases such as moves starting at position zero. Additionally, they addressed a formatting issue in player move output, ensuring cleaner and more accurate feedback for users. These targeted updates improved code maintainability and set the stage for more robust move validation, demonstrating a methodical approach to C programming and output formatting within a game development context.
