declare
Foo : String := ...;
begin
...
end;
Foo is allocated on the stack; size is taken from the initialization expression.
with Ada.Strings.Unbounded; use Ada.Strings.Unbounded;
declare
Foo : Unbounded_String; -- empty
begin
Foo := To_Unbounded ("hi"); -- allocated on the heap
Foo := Foo & To_Unbounded ("bye"); -- allocation grows
end;
-- deallocated.
