RE: question in list

[Timothy Johnson]

Here are two ways:

$a = 'a';
@b = qw(a b c);
#####
#(1)#    Iterate till found
foreach(@b){
   if($a eq $_){
      print "Found it!\n";
   }
}

#####
#(2)#    Use a hash

foreach(@b){
   $c{$_} = 1;
}

if($c{$a}){
   print "\$a is in there.\n";
}else{
   print "No it's not.\n";
}

Subject: question in list


Dear All,    
    I have a problem about the list value. 
    I have got a scalar say $a='a' and a list say @b = ('a', 'b','c');
    how can I check whether $a is one of the value in @b. Is there any easy
way to do it and I got lost in perl.com's piles of documentation.

Thanks
Alex
