Unit Tests and/or Case Tests for my changes

No new unit test was added.
The modified code was manually reviewed to ensure that the affected local variables are initialized before use.
This change is small and localized, and it is intended to avoid potential undefined behavior caused by uninitialized values.

What's changed?

Initialize local variables that may otherwise be used without guaranteed assignment on all control-flow paths.
Keep the change minimal by using explicit initialization at declaration.
Improve robustness and make the control flow safer and easier to reason about.
