given following 
===
$default_str = "good food";
$string1 = $default_string;

$string2 = $default_string;

$string3 = $default_string;

$string1 =~ s/o*/e/;
print $string1;

$string2 =~ s/o+/e/;

$string3 = ~ s/o/e/g;

print $string1;
print $string2;
print $string3;

what I don't understand is why does pattern substitution for $string1 and $string2 does not gave me the end results of "geed feed" ?

Doesn't 1 and 2 look for "o".. and for 1, it has a "*", which means "match 0 or more", right?

and for 2, it has a "+", which means match 1 or more times, right?

thanks in advanced
