Hi all,
Kindly look at the code below:
my ($bi, $bn, @bchrs);
my $boundry = "";
foreach $bn (48..57,65..90,97..122) {
$bchrs[$bi++] = chr($bn);
print "$bchrs[$bi]";
}
Output:
Use of unitialized value within @bchrs
Now when same code is written as
my ($bi, $bn, @bchrs);
my $boundry = "";
foreach $bn (48..57,65..90,97..122) {
$bchrs[$bi++] = chr($bn);
}
print @bchrs;
Output:
0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz
Why value is uninitialized in Case 1.
Thanks & Regards,
