I know how to read the key from the keyboard now but when I use the
Readkey to read the F3 key, it only show 0 for the key, and it is same

Math::Complex (and Math::Trig) has been part of core perl for quite
some time.
I would expect that you already have it.

You're trying to use the trinary like you would an if-then-else. You
want to instead use it in an assignment:
$type = ($type eq 'unknown') ? 'human' : 'both';

Don't put any spaces inside a variable name, especially when interpolating it.
print first line : $user = @{$ttys {$user}} \n;
print second

How do we get the length of a variable in bytes?
I see the length function returns length in characters.
unless you (From perldoc -f length):
use do { use bytes; length(EXPR) }
Nothing there would seem to indicate it cannot be used to get the
length in characters or bytes of an array.

My best guess at what you're looking for is the total number of bytes in
all the elements of an array. This can be achieved by manually
accumulating the lengths:

It is important to note that this returns the number of characters,
not the number of bytes (in this case they are the same since all of

As you can see it is normal Perl. The real magic happens inside the
length and other functions. They check the value of the hints global
variable ($^H) and change their behavior if the use bytes bit is
set. In Perl 5.10 we have been given the ability
