ASCII.... ^D
From ASCII table:

Code:
Oct       Dec       Hex       Char          
------------------------------------   
104       68        44         D
136       94        5E         ^

Hope this helps....

I may be wrong, but I think it may be this line:
Code:
 Oct   Dec   Hex   Char
 --------------------------
  004   4     04     EOT

For future reference, I got this from the ascii man page (helpful little devil, and a lot of people don't even know it exists...)

I found this out thru my professor which is what I was looking for:

ctrl-D at the keyboard is treated as an end of input from the keyboard. I had to check for cin.eof() for the ctrl-d signal.


thanks for your reply,
