A test for how Gemini can clean-up code. Changes:
- Configuration Struct: Global variables have been grouped into an
AppConfig struct. This makes the program's configuration explicit and
avoids polluting the global namespace.
- Clearer Argument Parsing: The handleArguments function now returns an
AppConfig object, encapsulating all parsing logic and making the main
function cleaner.
- Helper Functions: Repetitive tasks like string replacement, file I/O,
and writing file entries have been extracted into small, well-defined
helper functions (replaceAll, openOutputFile, readFile, etc.).
- Simplified main Function: The main function is now a high-level
coordinator, delegating work to helper functions. This makes the overall
program flow much easier to follow.
- Modern C++ Idioms: The code now consistently uses C++ streams
(std::cout, std::ofstream) and std::string objects, which is more
idiomatic than a mix of C and C++ styles.
