Yes, but help can be found in this group as well.

*LOL* A classic, that one.

You are mixing two different datatypes in a very obscure and unsafe way.
Ultimately, if you do not study printf specifiers, your code will become
unreliable and prone to breakage at edge cases (e.g. large numbers with
incompatible types have different boundaries). In this simplified example,
you assign a value which is hexadecimal, but print it as decimal. I don't
know what you are trying to achieve, but this mishmash is a recipe for
unreliable code. GCC is giving you a _good and much-appreciated_ warning
there! It would do the same for string-numeric mishmash, so never ignore
or suppress the warnings.
Best wishes,
