WebSep 28, 2007 · Here's a perfectly compliant C implementation: CHAR_BIT = 64. sizeof (char) == sizeof (short) == sizeof (int) == sizeof (long) (the unsigned counterparts are always the same size). It's possible for unsigned char to have the range: 0 through 2^64 -1. and at the same time have int with the range: -2^63 through 2^63 - 1. WebSo, bit_value = ( (uint8_variable>>BIT_NEEDED)&1) So this would shift the bit you need in LSB position, and the & operator would mask the other bits. Example: uint8_variable = 0110 1010 BIT_NEEDED=3 0110 1010 >> 3 = 0000 1101 0000 1101 & 0000 0001 = 0000 0001. I think this should work properly. Remember to count bits from 0. Share. Cite. Follow.

WebFeb 12, 2024 · You can use an std::bitset::operator[] to access the specifit bit. Keep in mind though, that [0] means the least significant bit, but we want to store them in the most significant -> least significant order, so we have to use the 7 - j instead of simply j :
WebJan 16, 2024 · However, for Boolean values, this is a bit wasteful (pun intended). Boolean types only have two states: true (1), or false (0). This set of states only requires one bit to store. However, if a variable must be at least a byte, and a byte is 8 bits, that means a Boolean is using 1 bit and leaving the other 7 unused.
