It's not unusual to have bool to be the size of int for performance purposes. If for specific purposes (say hardware simulation) you need a type with N bits, you can find a library for that (e.g. GBL library has BitSet class).

WebAug 12, 2024 · Bits are primarily used to represent data use and transmission speeds of internet, telephone, and streaming services. The bit rate refers to how many bits are transmitted per second. Bytes, on the other hand, are used to express storage sizes. 1 byte is equal to 8 bits. This means that one byte can represent 256 (2 8) different states. WebChanging the n th bit to x. Setting the n th bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n); Bit n will be set if x is 1, and cleared if x is 0. If x has some other value, you get garbage. x = !!x will booleanize it to 0 or 1. WebDec 14, 2010 · 4 Answers. Sorted by: 59. In general: value = (value & ~mask) (newvalue & mask); mask is a value with all bits to be changed (and only them) set to 1 - it would be 0xf in your case. newvalue is a value that contains the new state of those bits - all other bits are essentially ignored.
