in thread Word Counting

This definately isn't homework, heh...sometimes I wish I were still in school though. I know how to open and read files, but I don't understand part #3. How do I split on whitespace? You'd have to split each word into their own variable, that's the part I don't understand.

    You can use split to put the words into an array or a list: 
    my $line  = "This is a line of text";
my @words = split /\s+/, $line;

    Note that the /\s+/ bit technically isn't needed, because split defaults to splitting on whitespace.

    There's more info on split on Perldoc.

    Hope that helps,

    Use split(); e.g., 
    # Assuming %words is the hash where you keep all the words
$words{$_}++ for split /\s+/, $line;
