C++ int to bit array
WebDec 15, 2024 · For each bit in the value representation of the result that is indeterminate, the smallest object containing that bit has an indeterminate value; the behavior is undefined unless that object is of unsigned char or std::byte type. The result does not otherwise contain any indeterminate values. WebFor example, even though most implementations of C and C++ on 32-bit systems define type int to be four octets, this size may change when code is ported to a different system, breaking the code. The exception to this is the data type char, which always has the size 1 in any standards-compliant C implementation.

As a side note there's also std::dynamic_bitset, but am not 100% sure it made it into the standard. For vanilla C++, there's std::bitset. Bitset is very similar to vector (also known as bit_vector): it contains a collection of bits, and provides constant-time access to each bit.
WebA bit array (also known as bitmask, [1] bit map, bit set, bit string, or bit vector) is an array data structure that compactly stores bits. It can be used to implement a simple set data structure. A bit array is effective at exploiting bit-level parallelism in hardware to perform operations quickly.
