It's Ada Lovelace Day Learn the Ada Programming Language in 2021

Not being able to directly print an integer without calling a function to convert it to a string is awkward. The article presents this bit of code:

   with ada.Text_IO;
   use Ada.Text_IO;

   procedure Main is
      myNumber: Integer;
   begin
      myNumber := 123;
      Put_Line ( Integer'Image (myNumber) );
   end Main;
