Task
Loop over multiple arrays simultaneously
You are encouraged to solve this task according to the task description, using any language you may know.

Loop over multiple arrays (or lists or tuples ...) and print the ith element of each. Use your language's "for each" loop if it has one, otherwise iterate through the collection in order with some other loop.

Example, loop over the arrays (a,b,c), (A,B,C) and (1,2,3) to produce the output

aA1
bB2
cC3

Common Lisp

<lang lisp>(mapc (lambda (&rest args)

       (format t "~{~A~}~%" args))
     '(|a| |b| |c|)
     '(a b c)
     '(1 2 3))</lang>

Ruby

<lang ruby>['a','b','c'].zip(['A','B','C'], [1,2,3]).each {|i,j,k| puts "#{i}#{j}#{k}"}</lang>

Tcl

<lang tcl>foreach i {a b c} j {A B C} k {1 2 3} {

   puts "$i$j$k"

}</lang>
