Good catch. It will print "0x1234" but it should print "0x01020304".
My example has the same error. The conversion specification should be
"%02x", not just "%x".
--=20
My preferred quotation of Robert Louis Stevenson is "You cannot
make an omelette without breaking eggs". Not because I like the
omelettes, but because I like the sound of eggs being broken.
