See you are considering one bit of bit1, and printing it as signed integer. So what i think is that '1' bit will be treated as 1111 1111 while treating it as Signed Integer, and this is the binary representation of -1. Hence the result.
If you write it as unsigned int bit1:1, the result is 122. So my argument is correct. Try this and let me know. Correct me If m wrong.
