How do you find the sum and average of an array?

average=Σ(elements of the array)/number of elements in the array

1. Take n, a variable that stores the number of elements of the array.
2. Create an array of size n.
3. Iterate via for loop to take array elements as input, and print them.
4. Iterate via for loop to access each element of array to get the sum of all the elements.

How do you find the sum and average of an array in C++?

Algorithm to find average of N numbers stored in an array Using for loop, we will traverse inputArray from array index 0 to N-1. For any index i (0<= i <= N-1), add the value of element at index i to sum. sum = sum + inputArray[i]; After termination of for loop, sum will contain the sum of all array elements.
