Q. Program to print the sum of all the elements of an array.

Explanation

In 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.

Program to print the sum of all the elements of an array

Sum of all elements of an array is 1 + 2 + 3 + 4 + 5 = 15.

Algorithm

Declare and initialize an array.
The variable sum will be used to calculate the sum of the elements. Initialize it to 0.
Loop through the array and add each element of array to variable sum as sum = sum + arr[i].

Solution

Python

#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 
int main()
{
    //Initialize array 
    int arr[] = {1, 2, 3, 4, 5}; 
    int sum = 0;
    
    //Calculate length of array arr
    int length = sizeof(arr)/sizeof(arr[0]);
    
    //Loop through the array to calculate sum of elements
    for (int i = 0; i < length; i++) { 
       sum = sum + arr[i];
    }  
    printf("Sum of all the elements of an array: %d", sum);
    return 0;
}

Output:

Sum of all the elements of an array: 15

JAVA

public 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

<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
