My question is on the following three lines of code:

Hi,
I find that articles stating that 'placement new' constructs an object
on a pre-allocated buffer and so takes less time.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
