Hello Paul,

No!  The printf() family are pretty large.  You only need fputs() to
implement assert().  To ensure ANSI/ISO compliance, and pick up a few
tips from the old hands, you should get "The Standard C Library" by
P.J.  Plauger.  He also gives you permission to use his code beyond
mere "fair use".

Let me quote him from p.20 regarding assert().

"The macro must not directly call any of the library functions, such
as fprintf.  Nor may it refer to the macro stderr.  These names are
properly declared or defined only in the header .  The
program might not have included that header, and the header 
must not.  A program can define macros that rename any of the names
from another header, provided it doesn't include that header.  That
mandates that the macro call a function with a secret name to do the
actual output."

You're doing well! Keep up the good work.

Catch you later,
