$count+=7 But in @array[0] ??

$count+=7 But in @array[0] ??

$count+=7 But in @array[0] ??

(OP)
Hi
I´m new 2 Perl and I want to know how I
can increase an array from
@array[0] to @array[2] to @array[4] ond so on

It is simple with $count+=2 but how do I do it in some array

Thanks for your help

RE: $count+=7 But in @array[0] ??

Hello visitor,
welcome and I don't understand the question....  

Are you trying to simply increase the number of elements in the list?  If so,

push @array,1; # will add an element with the value of 1 to the end of the @array.


Or, are you wanting to increase the value of one element in an @array?  If so,....
@array = ('1','3','5','7','9');
# the second element is 3
$array[1]+=7;
# now, the second element is 10.


'hope this helps...

RE: $count+=7 But in @array[0] ??

Perl dynamically allocates space for arrays, so you don't have to worry about declaring the size like you would in C, for instance.  It acts more like a stack or a queue, which is why the push/pop functions are provided like goBoating suggested.  Simply assign a value to the new index and it will automatically create it for you.  This is one of the reasons I love Perl so much!

eg:
@array;
$array[0] = "new value";
$array[1] = "another value";
$array[2] = "one more";
