Perl range operator and printing of array

Posted on 2013-10-24

I was trying to populate an array with 100 elements having the values 1 through 100.  But I can not print out the contents of the array.  See the actual result I get below.  Am I using the correct sytax?  I am executing this with Strawberry Perl in Win 7.  Thank you for any insight.

@fred=[1..100];
print @fred;

The output:

C:\\perl_data>perl knit8.pl

ARRAY(0x39e6e8)

Your method worked printing all the elements in a ray with no space in between the values.
I tried also print "@fred"; - but this did not work either.

@fred=(1..100);
print "@fred";
#or
@fred=[1..100];
print "@{$fred[0]}";
#or
@fred=(1..100);
print "$_\n" for @fred;

So that last one worked the best. And the central issue would appear to be using paren to contain the .. defined range as opposed to square brackets.  With the brackets I had the same weird ARRAY(hex) output.  When defined with parens even the simple print "@fred";
works and formats properly.  Thank you.


@fred=(1..100);
print "$_\n" for @fred;

print "$_\n" for @fred;  # or    $"="\n"; print "@fred\n";
