This program duplicates standard input on standard output.

You are being mislead by the use of "char" in C. "char" sometimes refers to the 
equivalent of Ada's Character, and other times to the equivalent of 
System.Storage_Elements.Storage_Element or Ada.Streams.Stream_Element.

This is one of the latter cases. You should not be using Character, String, or 
Ada.Text_IO for this. I suggest you look at streams and Ada.Text_IO.Text_Streams.
