Thus, any assumption you are making about the internals of this class is just that - an assumption. If you want to convert an unsigned char to a bitset<8>, there is already an easy way to do that: unsigned char myChar = 0x0F; std::bitset<8> bs (myChar); WebI have been using a uint8_t flag and doing the bit manipulation myself.
