I have a ruby hash:
VALS = { :one => "One", :two => "Two" }
and an Array:
array2 = ["hello", "world", "One"]
Question: How can I populate a new array1 so that it only pulls in any values in array2 that match exactly the values in VALS?
For example...

The contents as sets:
array1 = VALS.values & array2 print array1
Output:
One
Here's an option:
hash = { :one.

Count() would work:
while(count(array1)){ if(somecondition1) array_push(array2,"Test"); elseif,"Test"); elseif(somecondition2) array_push(array2,"Test"); } until (count(array1) == 0)
Here's a test I did expanding upon your....

The function you're looking for is called array_merge
array array_merge ( array $array1 [, array $array2 for that, but this will work:
$array3 = array_keys(array_flip($array1) + array_flip($array2))
Set::merge.

In Objective-C, if array1 is copied onto array2 using mutableCopy, and suppose the code is done in main(), who is responsible for releasing the objects contained in the array? Is it main() or array2?

When you create array2 via -mutableCopy , you get an NSMutableArray ....
From the NSArray documentation are retained by the NSArray array1 .
Or array2?
Both array1 and array2 are responsible for releasing the objects.

You can do:
template <std::size_t size> void TheFunction(string (&Array1)[size], string (&Array2)[size....
Like this:
void TheFunction(string Array1[], string Array2[], int size automatically.
To take arrays of strings.

I am writting a Perl script to create pie graph using GD::Graph::pie with these arrays:

You almost certainly mean:

Less directly:
my @graph_data = (\Array1, $@array2); my @graph_data1 = (\Array1[0], $@array2[0]);
looks mad.

For this:
"such that array1[96] and array2[0] would be pointing to the same location."
you can do}; int* array2 = &array1[95];
In C++ you can use an int pointer as an int array, so getting the array2 to start at item....
