What is the difference between declaring "int[3] a = [1,2,3];"
and declaring "int[] a = [1,2,3];"? Is the first an array and
the second a range?
They are both arrays, just the former one has a fixed size and
the latter does not. Ranges require a way to iterate and
consume elements, meaning they cannot be fixed size.
I always thought that leaving the square brackets empty would
create an array of flexible size, it never occurred to me that
it was creating something else.
That's what it is, just a flexible array also happens to be an
array, whereas a fixed-size array is not one.
But a slice of a fixed size one yields a flexible one.. which
is why the ps[] thing works to create a range out of it.
Thank you guys so much for the explanation, it is all making more
sense now.
