	Besides the fact that EOF is control Z in dos, not control D, this code
won't work because the != operator has higher precedence than the =
(assignment) operator.  So what the code in the while parentheses says
is "if you entered EOF then store false in ch, else store true".  You
can fix this using parentheses: (ch = getchar()) != EOF)
