Re: Help me parse a long character

[Simon Johnston <skj@ACM.ORG>]

Use the Index function in Ada.Strings.Fixed, like so: the first bit will
get you the last name, and then the first name. You can then use the
resulting four values to substring your original to get two shorter
strings. Note this relies on at least one space between LASTNAME and
FIRSTNAME and a trailing space after FIRSTNAME - if this is not the case
then you'll have to add some code :)

   declare
      Start_Of_LASTNAME : Natural;
      End_Of_LASTNAME : Natural;
      Start_Of_FIRSTNAME : Natural;
      End_Of_FIRSTNAME : Natural;
   begin
      Start_Of_LASTNAME := Full_Name_String'First;
      End_Of_LASTNAME :=
Natural'Pred(Ada.Strings.Fixed.Index(Full_Name_String, " "));

      Start_Of_FIRSTNAME :=
Ada.Strings.Fixed.Index_Non_Blank(Full_Name_String(End_Of_LASTNAME ..
Full_Name_String'Last));
      End_Of_FIRSTNAME :=
Natural'Pred(Ada.Strings.Fixed.Index(Full_Name_String(Start_Of_FIRSTNAME ..
Full_Name_String'Last)));
   end ;

Subject:        Help me parse a long character

This is an easy one I'm sure. I'm in my first semester of programming....

I'm trying to parse a 40-character long string. They are formatted in the
 following way:

LASTNAME^^^^^^^^^^^^^^^^^FIRSTNAME^^^^^^      <--- the variable Full_Name

I'm not sure how to parse it into to two separate variables, first_name and
 Last_name.

I used the get_line procedure to get the string, so I have the
last_character
 position. How do I ignore the spaces in between?

Thanks !
