EIW Exercises: Perl

1. Install perl on your computer

You can find perl at: http://www.activestate.com/Products/ActivePerl/. Download and install the Windows version. IMPORTANT! Keep track of where perl is installed! By default it will be installed in c:/perl.

Verify that perl is installed correctly by running the perl interpreter from a DOs prompt (type in the command "perl"). If Perl is not in your path you need to set the PATH variable in your autoexec.bat file, ask for help if you don't know how to do this... Press F6 when you get perl running - this tells perl you are not giving it any input (it is looking for a perl program from standard input).

2. Write and run some perl programs

1. Write a perl program that converts degrees fahrenheit to celcius.

2. Write a perl program that prompts for a string and a number, then will output the string the number of times indicated (use the string repetition operator!).
