How do I access the last element of an array?

will be helpful for those in need length is fine if your array uses standard indexing. However, x[length(x)] will not necessarily return the last element if the array uses custom indexing.
A more general and explicit method is to use last, which will return the last element of an array regardless of indexing scheme:
code :
julia> x = rand(3)
3-element Array{Float64,1}:
 0.7633644675721114
 0.396645489023141 
 0.4086436862248366

julia> last(x)
0.4086436862248366
julia> lastindex(x)
3
julia> last(x)
0.4086436862248366

julia> x[lastindex(x)]
0.4086436862248366

julia> x[end]
0.4086436862248366

it fixes the issue There's lots of ways. Some are:
make MyArr a static variable of the MyClass class pass MyArr[i] as a parameter to the method call on MyArr[j] construct each object passing in a pointer or reference to the other instance

This might help you You could either write an iterator that would deal with your special case, or you iterate over it an deal with the special case:
code :
foreach ($array['response'] as $responses)
{
    isset ($responses[0]) || $responses = array($responses);
    foreach ($repsonses as $response)
    {
        # standard processing code per each item.
    }
}

Can't access an array within an array; instead, calls affect that number element in every array

I hope this helps . Because you have filled your graph with 10 references to one row.
to solve this just do it like this:
code :
function fill(){
    for (var i = 0; i < height; i++){
        var row = new Array();
        for (var k = 0; k < width; k++) {         
            row[k] = 0;
        }
        graph[i] = row;
    }

wish of those help I'm extremely new to programming in Perl, and new to the programming world in general. , You would need to write something like this...
code :
my @list;
open (my $csv, '<', $file) || die "cant open";
foreach (<$csv>) {
   chomp;
   my @fields = split(/\,/);
   push @list, $fields[1];
}

will be helpful for those in need Isn’t it easier to create a class that saves your variables (name, last name etc.) and then creat an ArrayList of that class type (ArrayList) and call the desired item and access the data you need
