Dead stores refer to assignments made to local variables that are subsequently never used or immediately overwritten. Such assignments are
unnecessary and don’t contribute to the functionality or clarity of the code. They may even negatively impact performance. Removing them enhances code
cleanliness and readability. Even if the unnecessary operations do not do any harm in terms of the program’s correctness, they are - at best - a waste
of computing resources.
Exceptions
This rule ignores initializations to -1, 0, 1, NULL, TRUE, FALSE and
