For 1-6, I wrote this, thinking that perhaps I was just making it too complicated:
When I run it, I see a strange problem.
It produces a list of 1s, (because the statement is always true, if there's another character that isn't EOF) and then when you hit Control-D (Thank you, thank you!) it prints the end statement.
The problem is that it always prints one extra 1!
That is, if I type a string of five letters into the keyboard, it will print six ones.
I don't see where the extra one is coming from, the only way to reach the printf statement is for there to be a character in the character stream. I think. Maybe. Perhaps. Probably. In my fantasy world.
So where is the extra 1 coming from?
P.S. Now I'm off to nail 1-8, which looks easy.

Gaurav, thank you, I'm using Mac OX X, 10.6.2, called Snow Leopard, and Control-D does indeed work.
Thank you again.

I did an assignment for sh scripting back in november, and I found it quite fun learning. I would like to retain this knowledge as I'm pretty sure it was my only scripting assignment, from now on in my programming course we won't be doing any scripting apart from the typical makefile scripts.

getc
GETS(3) Linux Programmer's Manual GETS(3)NAME
fgetc, fgets, getc, getchar, gets, ungetc - input of characters and strings
SYNOPSIS
#include <stdio.h>
int fgetc(FILE *stream);
char *fgets(char *s, int size, FILE *stream);
int getc(FILE *stream);
int getchar(void);
char *gets(char *s);
int ungetc(int c, FILE *stream);
DESCRIPTION
fgetc() reads the next character from stream and returns it as an unsigned char cast to an int, or EOF on end of file or error.
getc() is equivalent to fgetc() except that it may be implemented as a macro which evaluates stream more than once.
getchar() is equivalent to getc(stdin).
gets() reads a line from stdin into the buffer pointed to by s until either a terminating newline or EOF, which it replaces with '
