Good question in light of the inadequate coverage of I/O issues in the
Barnes Ada 95 text (pet peeve!). I discovered the following short-cut in
the Ada95 for C/C++ on-line guide at
http://lglwww.epfl.ch:80/Ada/Ammo/Cplpl2Ada.html
"A simple program below uses Text_IO to print a message to the screen,
including numerics!
These are achieved by using the types attribute 'Image which gives back
a String representation of
a value.
with Ada.Text_IO; use Ada.Text_IO;
procedure Test_IO is
begin
Put_Line("Test Starts Here >");
Put_Line("Integer is " & Integer'Image(2));
Put_Line("Float is " & Float'Image(2.0));
Put_Line("Test Ends Here");
end Test_IO;
It is also possible to use one of the generic child packages of Ada.
Text_IO such as
Ada.Text_IO.Integer_IO which can be instantiated with a particular type
to provide type safe
textual IO.
with Ada.Text_IO;
type My_Integer is new Integer;
package My_Integer_IO is new Ada.Text_IO.Integer_IO(My_Integer);
use My_Integer_IO;
