What will be the output of the following C# code?

static void Main(string[] args)
{
    int[] arr = new int[] {1, 2, 3, 4, 5};
    fun1(ref arr);
    Console.ReadLine();
 }
static void fun1(ref int[] array)
{
    for (int i = 0; i < array.Length; i++)
    {
        array[i] = array[i] + 5;
        Console.WriteLine(array[i] + " ");
    }
}
