Dear people,
I wrote the following code:
Code:
-module(stream).
-export([const_stream/1]).
const_stream(N) -> {N, fun() -> const_stream(N)}.
What it is supposed to do should be rather obvious (if not, I could, of course explain it  ).
When I try to compile it I get the following set of errors:
Quote:
./stream.erl:4: syntax error before: '}'
./stream.erl:2: function const_stream/1 undefined
So please could you tell me how to fix that code  |

Hi, wolfgke,
There is a syntax error before '}'. It is because you missed the 'end' when defining a fun() variable. The correct version of code should be like this:
Code:
-module(stream).
-export([const_stream/1]).
const_stream(N) ->
{N, fun() -> const_stream(N) end}.
 fun() -> a few lines of code end |
