Perl Tutorial 4 - Arrays: Basics

[IFoundMyUsername]

Yes. You can write $numWords = @words;

print $numWords;

and it will return 4.

[Raptilla]

Remember, you can also get the number of elements in an array by treating the array variable as a scalar. You don't have to use "@#array + 1".

[DARKlilution]

wait,in the second print,you wanted to show an array witch is the @ icon but you puted the $ icon but there where no error!!

what the hell is going on???

[EGuYPT]

agree!

[alexanderssson]

its the way it works.

[Ashfaqshinwary]

in first PRINT stmt he was showing you the full array at the output

but the second print stmt he was refering to the index entries of the array; & you might know that arrays in return hold simple variables (: ... thats y "$" was used !!

[Becomeageek]

It's because $numbers is a scalar reference to the @numbers array.

In fact, Perl automaticaly assign reference when an array is created.

You can make your own reference with : $ref = \@array;
