Subject: iterator/array question

Is there a way to iterate through an array, getting the index and the 
object at the same time?

For instance, right now I know two ways of going through an array:
array.each do |element|
  print element
end

for i in 0..(array.size - 1)  do |i|
  print array[i]
end

Is there a way to mix these two together? As in something like
array.each do |element, i|
  print element.to_s + "is at index " + i.to_s
end

without maintaining a counter through the array?
(Without doing this:
index = 0
array.each do |element|
  print element.to_s + "is at index " + index.to_s
  index += 1
end)

Thanks!
