it means... if you enter 3 times wrong input it should exit from the program...
here i am providing code please modify it
#!/user/bin/perl
print"enter the rang of array:\n";
chomp($c=<STDIN>);
while($i=1){
print"while loop round:$i\n";
if($i>3){
exit;
}
if($c =~ /^\[|[a-z,A-Z]+/){
print "it is invalid please enter digits\n";
#print"enter the rang of array:\n";
#chomp($c=<STDIN>);
}
elsif($c =~ /^[1-9]+/){
print "you are entered correct input\n";
last;
}
$i++;
}
@a=();
$b;
$1;
print"Enter the array:\n";
for($i=0;$i<$c;$i++){
chomp($b=<STDIN>);
$a[$i]=$b;
}
#for($i=0;$i<@a;$i++){
#print"the array $a[$i]\n";
#}
#print"the PSI ID's:";
foreach $val(@a){
#print"####$val###\n";
if($val=~ /^([a-z]+)\s?PSI\-ID\-?(\d+)/){
print"value=$2\n";
push(@b,$1);
push(@c,$2);
}
}
print"the pax id's with PSI:\n";
for($i=0;$i<=@b;$i++){
for($j=0;$j<=@c;$j++){
if($i==$j){
print"$b[$i] $c[$j]\n";

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
