10.4 violation for u8b + 2

Post by fmteau » Mon Jan 18, 2021 1:27 pm

Hello MISRA Bulletin Board,

I understand mixing signed and unsigned variables in arithmetic operations can really lead to unexpected results,
but I really fail to see what is the risk in adding a constant value of 2 (SLTR of signed char) to an unsigned 8-bit (char) variable.

Could you please elaborate what can possibly go wrong in this case?

Thanks in advance.
