Just for the sake of argument, you can also do it using the /g switch of
m//.
while($string =~ /,/g){
$num++;
}

The tr operator will translate one character to another. For example:
my $string = "abc";
$string =~ tr/a/d/;
print $string;
prints
dbc;
However, it also returns the number of changes it did. So, if you don't
give it anything to change to, you can count how many occurrences of a
character were in the string.
my $string = "a,b,c";
my $num = $string =~ tr/,//;
print $num;
prints 2.

like that. Thanks for any help.
