Now we looked at some of these loops in the context of Perl scripting, I am going to set to you a couple of exercises which you can feel free to do or ignore or exactly as you please. The answers as always to these exercises are found within the examples directory, on the CD. First task is to add five to each element of an array of numbers. And of course to show each element as it goes. Then show the months of the year and then show them in reverse. Once again the point here is not to stack a whole list of 24 print statements, but rather to use the techniques we've discovered in this particular chapter. Finally the last exercise is to take the number 2, and then keep doubling it and display the result, until it exceeds the number 1000.
