Q. Program to print the sum of all the elements of an array.ExplanationIn this program, we need to calculate the sum of all the elements of an array. This can be solved by looping through the array and add the value of the element in each iteration to variable sum. Sum of all elements of an array is 1 + 2 + 3 + 4 + 5 = 15. Algorithm
SolutionPython#Initialize array arr = [1, 2, 3, 4, 5]; sum = 0; #Loop through the array to calculate sum of elements for i in range(0, len(arr)): sum = sum + arr[i]; print("Sum of all the elements of an array: " + str(sum)); Output: Sum of all the elements of an array: 15 C#include Output: Sum of all the elements of an array: 15 JAVApublic class SumOfArray { public static void main(String[] args) { //Initialize array int [] arr = new int [] {1, 2, 3, 4, 5}; int sum = 0; //Loop through the array to calculate sum of elements for (int i = 0; i < arr.length; i++) { sum = sum + arr[i]; } System.out.println("Sum of all the elements of an array: " + sum); } } Output: Sum of all the elements of an array: 15 C#using System; public class SumOfArray { public static void Main() { //Initialize array int [] arr = new int [] {1, 2, 3, 4, 5}; int sum = 0; //Loop through the array to calculate sum of elements for (int i = 0; i < arr.Length; i++) { sum = sum + arr[i]; } Console.WriteLine("Sum of all the elements of an array: " + sum); } } Output: Sum of all the elements of an array: 15 PHP<!DOCTYPE html> <html> <body> <?php //Initialize array $arr = array(1, 2, 3, 4, 5); $sum = 0; //Loop through the array to calculate sum of elements for ($i = 0; $i < count($arr); $i++) { $sum = $sum + $arr[$i]; } print("Sum of all the elements of an array: " . $sum); ?> </body> </html> Output: Sum of all the elements of an array: 15
