Hello, I have some data that I would like to store in a hash of arrays, however this has proved to be a little complicated for me. I have written some test code below to investigate the behavior of this particular data type, and would like some help trying to understand it.
%Hash = ( ArrayInHash => [1,2,3,4], ); print "Array in hash: @$Hash{ArrayInHash}"; @Array = @$Hash{ArrayInHash}; print "\nArray: @Array"; $ArrayRef = $Hash{ArrayInHash}; @Array2 = @$ArrayRef; print "\nArray from ordinary scalar reference: @Array2"; print "\n\nTrying a foreach loop with the hash"; foreach(@$Hash{ArrayInHash}) { print "\n$_"; } print "\n\nTrying a foreach loop with the scalar array reference"; foreach(@$ArrayRef) { print "\n$_"; }
This produces:
Array in hash: Array: Array from ordinary scalar reference: 1 2 3 4 Trying a foreach loop with the hash Trying a foreach loop with the scalar array reference 1 2 3 4
Why didn't the first two print statement or foreach loop act on the array? There's got to be a better way to access the array besides setting the reference to an ordinary scalar first. Thanks
