[erlang-questions] A silly one?

[Fred Hebert]

The problem here is that you're using the function wrong.
  io:format("fac of ~p is ~p~n", N, Fac).
should be
  io:format("fac of ~p is ~p~n", [N, Fac]).

io:format takes only two arguments in your case, so the parameters to the
string need to be wrapped in a list.
