Hey

one more question that how to check whether the element in an array is a number or not . is there any function in perl

[davido]

See Scalar::Util, and its function "looks_like_number". The module is core, meaning it ships with Perl.

[2teez]

See looks_like_number in Scalar::Util like thus:

use Scalar::Util qw(looks_like_number);

 for(qw(1 perl 25 monks)){
   looks_like_number $_ ? print $_," is a Number",$/ 
                        : print $_," is not a Number",$/;
 }

Update:
Awooooshhhh! davido, beat me to it.....

[davido]

Yeah, but I left out the example, which you thoughtfully provided. ...or I left it as an exercise for the reader to figure out. ;)

what i want to do is that check whether the array cell has a number or not , if yes execute my block of code else not i.e.

 if( $array[$i] == number )
{
my block of code ;
}
