I was amazed to see how simple Perl makes it to read the lines of a file into an array.

#!/usr/bin/perl
open(I, “flavors.txt”);
@flavors = <I>;

With just two lines of code, you are ready to do some string munching. You can then run through the elements in the array with a loop similar to the following.

for($i=0; $i<@flavors.length; $i++) {
@flavors[i] =~ s/•//;
}

I would enjoy seeing some other ways to iterate through the array.
