Wow, C looks like a lot of work !!!!!
... preceding Ada statements
declare -- scope of array_called_p
type my_array_type is array ( positive range <> ) of integer;
array_called_p : my_array_type ( 1 .. variable );
begin -- scope of array_called_p
... Ada statements that use array_called_p
end; -- scope of array_called_p
... following Ada statements
In general, Ada rarely requires pointers.
