Sum and Average of Array Elements (C#.net)

The following code shows you how to sum up the array elements and how to average the array elements.

Code

public static void Main(string[] args)

{

    int[] arr = { 1, 2, 3, 4, 5 };

    int size = arr.Length;

    sumAverageElements(arr, size);

}

public void sumAverageElements(int[] arr, int size)

{

     int sum = 0;

     int average = 0;

     for (int i = 0; i < size; i++)

     {

          sum += arr[i];

     }

        

     average = sum / size; // sum divided by total elements in array

     Console.WriteLine("The Sum Of Array Elements Is : " + sum);

     Console.WriteLine("The Average Of Array Elements Is : " + average);

}

Output of the program is:

The Sum Of Array Elements Is : 15

The Average Of Array Elements Is : 3
