I'm guessing this should be
std::cout << "Optimal CRC-8 : "  << std::hex << (unsigned)crc_8()
    << std::endl;
The way iostreams format chars is most likely not what you wanted.
True enough - and that includes signed vs. unsigned chars (both are
handled the same, at least with my compiler).
The result needs to be put into an unsigned *int* for cout to display the
numeric value.
Sorry, I don't understand what you're saying... 

std::cout << "Optimal CRC-8 : "  << std::hex << (unsigned)crc_8()
     << std::endl;

is the same as 

std::cout << "Optimal CRC-8 : "  << std::hex << (unsigned int)crc_8()
     << std::endl;

AFAIK.
