perl-data from file save to multidimensional array
i have a file,like
1 3
4 5
6 7
8 9
i want to save it into an array.
and then i want to get every element, because i want to use them to calculate. for example: i want to calculate 1 + 3.

it will show all rows. but i want only one element.
or
it is not yet correct.
anyone has ideas?

gnutls_fingerprint
gnutls_fingerprint(3) gnutls gnutls_fingerprint(3)NAME
gnutls_fingerprint - calculate the fingerprint of the given data
SYNOPSIS
#include <gnutls/gnutls.h>
int gnutls_fingerprint(gnutls_digest_algorithm_t algo, const gnutls_datum_t * data, void * result, size_t * result_size);
ARGUMENTS
gnutls_digest_algorithm_t algo
is a digest algorithm
const gnutls_datum_t * data
is the data
void * result
is the place where the result will be copied (may be null).
size_t * result_size
should hold the size of the result. The actual size of the returned result will also be copied there.
DESCRIPTION
This function will calculate a fingerprint (actually a hash), of the given data. The result is not printable data. You should convert it
to hex, or to something else printable.
This is the usual way to calculate a fingerprint of an X.509 DER encoded certificate. Note however that the fingerprint of an OpenPGP is
not just a hash and cannot be calculated with this function.
RETURNS
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise an error code is returned.
