Is it possible to create a data type of length one bit in C

Question

Esentially I want to create a data type uint1_t. Is that even possible?

I know the size of the bool data type is one byte. But boolean values only need

Answer 1

No. 8 bits is the minimum size for a type. You can use a bit field to combine multiple "small" elements together if you really needed sub-byte storage.

However this is rarely a big deal. Machines have lots of memory and it is rarely necessary to worry about this kind of memory waste.
