Please forgive my lack of knowledge of C, i am using a tutorial at Howstuffworks.com to see if i want to devote more time to learning it. On the current "lesson" they have me enter the attatched program, compile and run it. the prog. is supposed to allow the user to enter text and then signal eof by pressing CTRL-D. however, this does nothing except put the symbol for that on the screen. can anyone help me with this? basically i think what i need is to know the end of file signal for windows xp.
