Hi there,
Very new to PERL (chapter 5 Learning PERL edition 2!!) but I am determined
to master this!! Or at least be good at it!!
I'm having trouble grasping the code below. I know it's a small snippet but
I think it's important.
Can you please explain the $count variable and how the %count came about?
chomp (@words = <STDIN>); # I understand this line as in you are reading in
all the words
foreach $word (@words){ # for every element of the array @words..........
$count {$word} = $count {$word} + 1; # or $count {$word}++ # I get a
bit lost here!! Is $count the value of the key $word in a hash?
}
foreach $word (keys %count) {#How did %count come about?
print "$word was seen $count {$word} times\n";
}
Thanks again
B
