make all
NOTE: this version is a fixed version for modern C compilers. See the Alternate code section below for how to use the original and why one might wish to do so.
./westley
Also try:
./try.sh
to show the code with followed by the result so you can truly see the magic.
This version is the original which might not work as you expect nowadays.
make alt
To see if your compiler has the problem described in the Judges’ remarks below, try:
./westley.alt
Does it show the same output as westley
?
Your compiler must parse
#define _ -a
-_
as --a
and not -(-a)
or some other tokenized form. Some strictly
conforming ANSI C Preprocessors may object to this: for such
compilers, you can elide the non-standard token-pasting requirement
by changing the #define line to:
#define _ F-->00||F-OO--;
This is what the modified code in westley.c does whereas the alt code is the original.
You might enjoy looking at the output of:
cc -E westley.alt.c
