Thanks all .
Hello,
But I found an another question :
If I wrote this script like this :
#!/usr/bin/perl
use warnings;
use strict;
while (<DATA>){
@lines = $_;
You are assigning one scalar value to the whole array the array will
only ever have one element in it.
You need to append each new scalar value onto the array:
push @lines, $_;
Or you could just assign the whole file in one go:
my @lines = <DATA>;
print "$lines[rand @lines]";
}
__DATA__
uriel
daniel
joel
samue
It would not display the random element of the array
Why ?
Or if I want to display the random element of the array like this ,what
should I do ?
