Describe the contribution
Fixes #43
Removes redundant and inconsistent comments (e.g. /* end of function */)
There were also a few cases of unnecessary empty lines (e.g. on the last line before the closing brace of a function) and also missing empty lines (e.g. between functions) which were corrected. Some of these empty lines trigger the CI format checks.
I've left the commits separated for now to make life easier for whoever reviews this. I can squash them if/when this is ready for merge.

Testing performed
None (comment and whitespace changes only).

Expected behavior changes
No impact on behavior.
These updates will reduce clutter and inconsistency in the code, improving readability.
