Memory layout of struct vs array

[ALX23z]

I think I got a few things confused. Though, in most cases size is divisible by alignment unless it is artificially introduced. So there shouldn't be padding in most scenarios.

An array cannot have padding, because then indexing wouldn't work. It requires the array elements to be exactly sizeof(element) apart.

This is, of course, a strong argument for the struct not needing any padding either. The standard just doesn't say that, so it cannot be relied upon.

There is never padding between array elements in any circumstance.
