Is "stdio.h" necessary?

There is (https://github.com/srdja/Collections-C/blob/master/src/include/cc_ring_buffer.h#L13) the line #include <stdio.h>.
I haven't found any printf/scanf in the code.
Also tried to remove this line and the code compiled correctly, therefore, I think it is unnecessary.

Yeah, definitely shouldn't be there. I guess it's a leftover from printf debugging.
