Here's a working copy of for.pl from chapter six of the exercise files and you'll notice that I have an array that has five strings in it and these five strings are created with the quote word operator and the strings are the words one, two, three, four and five. In this case, I'm iterating through the array using the for loop and so when I run this you'll see it lists these strings one, two, three, four and five using the say function there in the for loop. So the syntax of the for loop is borrowed directly from C. It takes three arguments and the arguments are separated by semi-colons. So you can see them here my $i = 0. That's the initializer.
