That's why working with strings in C/C++ is a nightmare! strcpy/strcat,++,--
and so on... Look at some real world C/C++ code handling strings !

For memory, a string in Ada is:

   type String is array (Positive range <>) of Character;

And you can do something like:

   function Some_Value return String is
   begin
      return "...";
   end Some_Value;

   S1 : constant String := "a long string";
   S2 : constant String := "this is definitly " & S1 & Some_Value;

   S3 : constant String := S1 (S1'First + 2 .. S1'First + 5);

Pascal.
