How can I split a word into its component letters?

Question

I am working with Perl and I have an array with only one word:

@example = ("helloword")

I want to generate another array in which each element is a letter from the word:

@example2 = ("h", "e", "l"...)

I need to do that because I need to count the numbers of "h", "e"... How can I do this?

Answer 1

To count how many times letter occurred in a string,

print "helloword" =~ tr/h//; # for 'h' letter

otherwise you can split string and assign list to an array,

my @example2 = split //, $example[0];
