N'th

From Rosetta Code
Revision as of 17:34, 1 April 2014 by rosettacode>Mwn3d (+Java)
Task
N'th
You are encouraged to solve this task according to the task description, using any language you may know.

Write a function/method/subroutine/... that when given an integer greater than or equal to zero returns a string of the number followed by an apostrophe then the ordinal suffix.
Example returns would include 1'st 2'nd 3'rd 11'th 1001'st

Task

Use your routine to show here the output for at least the following (inclusive) ranges of integer inputs: 0..25, 250..265, 1000..1025

Note: apostrophes are now optional to allow correct apostrophe-less English.

Ada

<lang Ada>with Ada.Text_IO;

procedure Nth is

  function Suffix(N: Natural) return String is
  begin
     if    N mod 10 = 1 and then N mod 100 /= 11 then return "st";
     elsif N mod 10 = 2 and then N mod 100 /= 12 then return "nd";
     elsif N mod 10 = 3 and then N mod 100 /= 13 then return "rd";
     else return "th";
     end if;
  end Suffix;
     
  procedure Print_Images(From, To: Natural) is
  begin
     for I in From .. To loop

Ada.Text_IO.Put(Natural'Image(I) & Suffix(I));

     end loop;
     Ada.Text_IO.New_Line;
  end Print_Images;
  

begin

  Print_Images(   0,   25);
  Print_Images( 250,  265);
  Print_Images(1000, 1025);

end Nth;</lang>

   every writes(" ",nth(1000 to 1025) | "\n")
