In PERL programming we need to crearte this code: we ca use either (file, references to array, hash, associative arrays, modules, exporting) here is the question: Introduction When you export symbols by default, you can populate the @EXPORT array, which means that anyone that you use your module will receive these symbols without having to ask for them. This is referred as “polluting” the caller’s namespace. Problem Prepare the program that send to three friends messages for your celebration and invite them for visiting you (address: 100 Oth way, Pittsburg). The message will be: The name of friends are: Marry, Ann, George. The caller is Peter. Output Dear ……(Mary), I celebrate my birthday and I would love you to come to dinner. Address is: (100 Oth way, Pittsburg ) on next Monday. Thanks, Peter Hint : You have to use, hashes for name and address, @EXPORT_OK and module.
