Static variable inside of a function in C
... the static int x (scope) part of the statement actually applies where you read it, somewhere INSIDE the function and only from there onwards, not above it inside the function.

How to avoid annoying error “declared and not used”
...and be sure to use everything you declare or import. It makes it easier to read code written by other people (you are always sure that all declared variables will be used), and avoid some possible dead code.
But, if you really want to skip this error, you can use the blank identifier (_) :
