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

Program to print the sum of all the elements of an array on fibonacci, factorial, prime, armstrong, swap, reverse, search, sort, stack, queue, array, linkedlist, tree, graph etc.

## 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.

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

### Algorithm

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

### 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

```<!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
```
