Is it possible to convert bitset<8> to char in c++?

unsigned long i = mybits.to_ulong(); 
unsigned char c = static_cast<unsigned char>( i ); // simplest -- no checks for 8 bit bitsets

Something along the lines of the above should work. Note that the bit field may contain a value that cannot be represented using a plain char (it is implementation defined whether it is signed or not) -- so you should always check before casting.

char c;
if (i <= CHAR_MAX) 
c = static_cast<char>( i );
