How do I check if a list is empty?
...ient if the array is of a significant size. Also, typically, you would not allocate memory for an empty array (pointer remains null), so it makes no sense to attempt to get its length. I am not saying that len(a) == 0 is not a good way of doing it, it just does not scream 'C' to me when I see it.

How to convert vector to array
...ray using the size() function of the std:vector you'll need to use new or malloc to do that. As it was already pointed out (by you) that double arr[v.size()] is not valid. Using vector in place of new is a good idea, but the entire point of the question is how you can convert a vector into an array...

...k space" error - and looking at the emulator properties, the default space allocated for internal storage is 800MB which seems low.
Solution, therefore was to increase this (I went to 4GB). Oddly the emulator still boots with the same disk space warning but factory resetting it (Settings --> Bac...
Concatenate two slices in Go
...mmodate the new elements.
If it does not, a new underlying array will be allocated. Append
returns the updated slice. It is therefore necessary to store the
result of append, often in the variable holding the slice itself:
slice = append(slice, elem1, elem2)
slice = append(slice, anotherSlice...
