WebFeb 20, 2024 · A boolean is actually 1 byte. But alignment may cause 4 bytes to be used on a 32-bit platform or 8 bytes on a 64-bit platform. This old trick comes from the observation that allocated memory takes up at least 4 or 8 bytes, and are aligned in the way that the least significant bit or three will be zero. WebFeb 17, 2024 · Correct, a bool will use at least 1 byte of storage. This applies when storing a bool in a structs or the raw primitive type.
