How to add two binary numbers using bitwise AND

I like to know how to add two binaary numbers using bitwise AND
something like that:
$bin_1 = 1011101000001
$bin_2 = 1000101010101
$result = 1000101000001

basically user enter two decimal numbers and code change those numbers
to binary then using bitwise prints the value/result the convert the
value to hex numbers.
Thanks in advance..

That's not addition.

Look up "bitwise and" in perlop.

Use the 'and' ('&') operator:

#!/usr/local/bin/perl
use warnings;
use strict;

my $bin_1 = 0b1011101000001;
my $bin_2 = 0b1000101010101;
my $result = ($bin_1 & $bin_2);

printf " bin_1: %13b (%d)\n bin_2: %13b (%d)\nresult: %13b (%d)\n",
$bin_1, $bin_1, $bin_2, $bin_2, $result, $result;

__OUTPUT__

bin_1: 1011101000001 (5953)
bin_2: 1000101010101 (4437)
result: 1000101000001 (4417)

See 'perldoc perlop' and search for "Bitwise And" and "Bitwise String
Operators".

This is the second question I've read in two days involving extraneous
changing of number bases. Did I miss a memo?

It's just as easy to say
5 & 3 = 1
as it is to say
0101 & 0011 = 0001

Second, if I remember correctly, the use of bases in perl is almost
entirely limited to input and output. perl has no particular need
to take a decimal number, explicitly convert it into binary, and
then explicity convert it into hex.

In addition to the other answers you got, you can do this as strings as
well:

print "1011101000001" & "1000101010101";

The good thing about this is that it is not limited to 32 or 64 bits.
The bad thing is that if the strings aren't the same length they will
be aligned in an unintuitive (for numbers) manner.

And or course the answer is a string rather than a number. Whether that is
good or bad depends on what you want.
