For example in your code, it will print success if $d='de' and $e = '' even though it should print false according to the OP's original intent. Depending on what you know about the data, that will be in those variables however, you could probably do what you are intending, but joining both sides with a common delimiter and then comparing them. For example:

if ( join("->",$a,$b,$c,$d,$e) eq join '->',qw(a c c d e)) {
    print "success\n";
}
else {
    print "failure\n";
}
