Directions: Write a recursive function to calculate the product of
the components of a vector. Assume at least one component exists.

Declarations: apvector<int> Numbers;
              int subscript = Numbers.length() - 1;
              int product;

void getProduct(const apvector<int>& Numbers, int subscript,
                int& product)
{
    if(subscript == 0)
        product = Numbers(subscript);
    else
    {
        getProduct(Numbers, subscript - 1, product);
        product *= Numbers[subscript];
    }
}
