Explanation:

By adding up each element in an array and dividing the amount by the number of elements, one may determine the array’s average.

Steps:

  1. Input the Array and Its Size:
    • Take the number of elements (n) and the elements of the array as input.
  2. Initialize a Variable for Sum:
    • Set a variable sum = 0 to store the cumulative sum of the array elements.
  3. Calculate the Sum of Elements:
    • Use a loop to iterate through the array and add each element to sum
  4. Compute the Average:
    • Divide sum by n to calculate the average: average = sum / n
  5. Output the Result:
    • Print or return the calculated average.
