WebApr 3, 2024 · The underlying type of a bit field must be an integral type, as described in Built-in types. If the initializer for a reference of type const T& is an lvalue that refers to a bit field of type T, the reference isn't bound to the bit field directly. Instead, the reference is bound to a temporary initialized to hold the value of the bit field. WebThe variables defined with a predefined width are called bit fields. A bit field can hold more than a single bit; for example, if you need a variable to store a value from 0 to 7, then …
