1 method should repeatedly ask a user for a number (up to 10 total numbers) or they can stop early by entering 0 This method
        should return an array with the users input numbers

    1 method should take an array as a parameter, copy that array and double each element, and return the copy array

    1 method should display the original

**Write the program without any class scoped variables**

To make this easier, if the user does not enter all 10 numbers you do not have to keep track of the exact number they entered For more of a challenge you
    can grow the array as the user is entering numbers

{`enter code here`
            //Declarations
            int[] numberlist = new int[11];
            double[] doublelist = new double[11];
            Array.Copy(numberlist, doublelist, numberlist.Length);
            int length = numberlist.GetLength(0);
            const int end = 0;
            int count = 0;

            Console.Write(" Enter 10 numbers to convert to double n PRESS 0 TO ENDn ");
            Console.Write("____________________________________________________________nn");

            do
            {

                //get user input
                for (int i = 1; i < numberlist.Length; i++)
                {
                    Console.Write("| Enter next number: ");
                    numberlist[i] = Convert.ToInt32(Console.ReadLine());


                }

                Console.Write("                          Results:n");
                Console.Write("n____________________________________________________________nn");
                //print array
                for (int i = 1; i < numberlist.Length; i++)
                {
                    Console.WriteLine($"Number at index ({i}) =  {numberlist[i]} ");

                }

                Console.ReadKey();


            } while (count != end);
        }
    }

}
