Undefined, because a variable-argument function is used
without a prototyped declaration.
Also implementation-defined, because the final line of text
output is not terminated with a newline.
Also either (1) "semi-undefined" because a C90 int-valued
function returns without returning a value, or (2) implementation-
defined because a C99 compiler must diagnose a function definition
without return type, and *if* it translates the program anyhow it
gives it an implementation-defined meaning.
... but the answer you're probably looking for is "8", and
the explanation will be found in the low-numbered pages of your
C textbook -- you know, that unopened volume you've been carrying
around. Open it (it won't bite you), and see what it has to say
about "integer constants" or some similar term.
