Bit Manipulation

Learn how to manipulate bits with the '<bit>' header.

The header <bit> supports functions to access and manipulate individual bits or bit sequences.


Thanks to the new type std::endian, you get the endianness of a scalar type. Endianness can be big-endian or little-endian. Big-endian means that the most significant byte is the furthest left. Little-endian means that the least significant byte is furthest left. A scalar type is either an arithmetic type, an enum, a pointer, a member pointer, or a std::nullptr_t. The class endian provides the endianness of all scalar types:
