Loops/Foreach

Loops/Foreach
You are encouraged to solve this task according to the task description, using any language you may know.

Loop through and print each element in a collection in order. Use your language's "for each" loop if it has one, otherwise iterate through the collection in order with some other loop.

Common Lisp

(loop for i in list do (print i))

Forth

create a 3 , 2 , 1 ,
: .array ( a len -- )
  cells bounds do  i @ .  cell +loop ;     \ 3 2 1

Haskell

forM_ collect print

Java

Works with: Java version 1.5+

<java>Collection<Type> collect; ... for(Type i:collect){

  System.out.println(i);

}</java> This works for any array type as well as any type that implements the Iterable interface (including all Collections).

JavaScript

This works for any object, as well as arrays.

for (var a in o) print(o[a]);

Logo

foreach [red green blue] [print ?]

OCaml

List of integers: <ocaml>List.iter

 (fun i -> Printf.printf "%d\n" i)
 collect_list</ocaml>

Array of integers: <ocaml>Array.iter

 (fun i -> Printf.printf "%d\n" i)
 collect_array</ocaml>

Perl

<perl>foreach $i (@collect) {

  print "$i\n";

}</perl> The keyword for can be used instead of foreach. If a variable ($i) is not given, then $_ is used.

PHP

<php>foreach ($collect as $i) {

  echo "$i\n";

}</php>

Python

<python>for i in collect:

  print i</python>
