AI Summary: This is a 'Good First Issue' aimed at new contributors to the Hiero C++ SDK. It involves renaming poorly named loop variables (`txxx`, `txxxx`) in `AccountAllowanceSerializedExample.cpp` to more descriptive names, improving code readability for those learning how the SDK handles transaction serialization. Basic C++ and Git knowledge are sufficient.
