RE: [Boost-Users] Re: CRC problem with 8 bit truncated polynomial
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

Thanks to Jim and Vladimir you are both correct. There is no problem with the algorithm. I just had a problem outputting the value correctly to the command line. I appreciate the help. Regards, Victoria

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. - Volodya
