Create a program named integerfacts whose main() method declares an array of 10 integers.
call a method named fillarray to interactively fill the array with any number of values up to 10 or until a sentinel value (999) is entered. if an entry is not an integer, reprompt the user.

call a second method named statistics that accepts out parameters for the highest value in the array, lowest value in the array, sum of the values in the array, and arithmetic average.
in the main() method, display all the statistics in the following format: note: the inputs were 1, 11, and 999
the array has 2 values
the highest value is 11
the lowest value is 1
the sum of the values is 12
the average is 6
using static system. console;
class integerfacts{ static void main() { // write your main here } public static int fillarray(int[] array) { } public static void statistics(int[] array, int els, out int high, out int low, out int sum, out double avg) { } }
