The object it's inside will still take up at least one byte.
reply sizeof(struct {bool a:1;}) == sizeof(char);Amortization.
replyIf one Boolean must be a byte then 8 must be eight bytes. Which is not true. A boolean can be 1/8th of a byte which is a meaningful distinction.
3^5 is 243 so one could also call an optional Boolean 1/5th of a byte, though 1/4 is so much simpler to read and write.
replyUm, no. Please show me how you can fit 255 possible states in something smaller than a byte by using bitfields.
replyI was quoting the first paragraph, where it says a single normal bool takes a byte.
