Your code does not make sense.

Assuming, I don't know number of elements in @sss
The number of elements in @sss is just @sss in a scalar context: my $number_in_array_sss = @sss;

my $number_in_array_sss  = @sss;

print scalar(@sss). " ". $num\n";

UPDATE: more code below: 
#!/usr/bin/perl -w
use strict;
use Data::Dumper;

my @sss = ("1","3","4");
my $reee = [];

foreach my $entry (@sss)
{
    push (@$reee, $entry);
}

# this is to show various uses of scalar() and that
# the dot (concatenation) operator forces scalar context

print "\$ree has ",scalar(@$reee)," elements\n";
print "\$ree has ".@$reee." elements\n";
print ''.@$reee." elements\n";
print "each element is: @$reee \n";
print Dumper \$reee;

#PRINTS:
#$ree has 3 elements
#$ree has 3 elements
#3 elements
#each element is: 1 3 4 
#$VAR1 = \[
#            '1',
#            '3',
#            '4'
#          ];

# To accomplish the above is only one Perl statement!!

# No "foreach" or "for" loop is needed, 3 lines of code
# becomes one line of code. I do not count blank lines
# or lines with just braces "{}" as "lines of code".

my @aaa = (1,5,7);   # like @sss, repeated for clarity
                     #   and using different numbers.
my $bbb = [@aaa];    # this means: 
                     #   allocate some memory and assign its
                     #   reference to $bbb.
                     # The array, @aaa is copied to that
                     #   memory referenced by $bbb. 
print Dumper \$bbb;

#prints
#$VAR1 = \[
#            1,
#            5,
#            7
#          ];
