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.

getchar
getc(3s)getc(3s)Name
getc, getchar, fgetc, getw - get character or word from stream
Syntax
#include <stdio.h>
int getc(stream)
FILE *stream;
int getchar()
int fgetc(stream)
FILE *stream;
int getw(stream)
FILE *stream;
Description
The function returns the next character from the named input stream.
The function is identical to (stdin).
The function behaves like but is a genuine function, not a macro. It may be used to save object text.
The function returns the next word (in a 32-bit integer on a VAX-11 or MIPS machine) from the named input stream. It returns the constant
EOF upon end of file or error, but since that is a good integer value, feof and should be used to check the success of The assumes no spe-
cial alignment in the file.
Restrictions
Because it is implemented as a macro, treats a stream argument with side effects incorrectly. In particular, `getc(*f++);' doesn't work as
expected.
Diagnostics
These functions return the integer constant EOF at end of file or upon read error.
A stop with message, `Reading bad file', means an attempt has been made to read from a stream that has not been opened for reading by
