After some debugging, I've come up with a sample program that 
illustrates what is going on:

#include <stdio.h>

int main()
{
  int ch;
  printf("Prompt 1: ");
  ch = getc(stdin);

  printf("\nPrompt 2: ");
  ch = getc(stdin);
}

Compile and run the program. At the first prompt, press ctrl-z. The 
second prompt is printed and the program immediately exits. This is 
because the eof flag in stdin has been set from the first getc, thus an 
EOF is returned without even checking the keyboard.

Is it intentional that pressing ctrl-z disables all further keyboard input 
from functions like getc() that operate with a FILE pointer?
