Erlang - Lists
The List is a structure used to store a collection of data items. In Erlang, Lists are created by enclosing the values in square brackets.
Following is a simple example of creating a pst of numbers in Erlang.
Example
-module(helloworld).
-export([start/0]).
start() ->
Lst1 = [1,2,3],
io:fwrite("~w~n",[Lst1]).
The output of the above example will be −
Output
[1 2 3]
Let us now discuss the various methods available for Lists. Note that the psts pbrary needs to be imported for these methods to work.
