Find Sum and Average of the Array Elements in C++

Hello Everyone!

In this tutorial, we will learn how to find the Sum and Average of the Array elements, in the C++ programming language.

Arrays in C++

In Programing, `arrays` are referred to as structured data types. An array is defined as a finite ordered collection of homogenous data, stored in contiguous memory locations.

For developing a better understanding of this concept, we will recommend you visit: https://www.studytonight.com/c/arrays-in-c.php, where we have discussed this concept in detail.

The below given commented code demonstrates how to access the elements of the array in C++.

Code:

``````#include <iostream>
using namespace std;

int main()
{
cout << "\n\nWelcome to Studytonight :-)\n\n\n";
cout << " =====  Program to find the Sum and Average of the Array elements ===== \n\n";

//i to iterate the outer loop and j for the inner loop
int i, n;

//declaring sum and average as double because average can be a fractional value
double sum=0, average=0;

cout << "\n\nEnter the number integers you want in an array: ";
cin >> n;

//Declaring an array containing 'n' integers
int arr[n];

cout << "\n\n Enter " << n << " integers into an array :\n\n";

for (i = 0; i < n; i++)
{
cout << " Enter arr [ " << i << " ] : ";
cin >> arr[i];
}

cout << "\n\n The Elements of the Array are: \n\n";

for (i = 0; i < n; i++)
{
cout << " arr [ " << i << " ] = " << arr[i] << endl;
sum += arr[i];
}

average = sum/n;

cout << "\n\n The Sum of the Elements of the Array is : " << sum << "\n\n";

cout << "\n\n The Average of the Elements of the Array is : " << average << "\n\n";

cout << "\n\n";

return 0;
}``````
