## Q. Write a program to find sum of elements in a given array.

Array :- An array is a collection of data items, all of which are of the same type, using a common name.
For Example :-
input : arr[]={ 8, 9, 1, 2, 4 }
output : 24

So as we can see that the sum of elements in arr[] = {8, 9, 1, 2, 4 } is 24 so the output is 24.

## Array Sum Algorithm

```START
Step 1 : Take an array Arr and define its values
Step 2 : Loop for each value of Arr
Step 3 : Add each element to 'sum' variable
Step 4 : After the loop finishes, display 'sum'
STOP
```

# Array Sum Program

• C
• C++
• Java
• Python
• C#
• PHP
• ```#include <stdio.h>
int main() {
int array[10] = {9, 8, -15, 30, 0};
int sum, loop;
sum = 0;
for(loop = 9; loop >= 0; loop--) {
sum = sum + array[loop];
}
printf("Sum of array is = %d", sum);
return 0;
}
```
```#include <bits/stdc++.h>
using namespace std;
int main()
{
int i, num[5]={9, 8, -15, 30, 0}, sum=0;
for(i = 0; i < 5; ++i)
{
sum += num[i];
}
cout << "Sum of array is =  " << sum;
return 0;
}```
```class LFC
{
static int arr[] = {9, 8, -15, 30, 0};
// method for sum of elements in an array
static int sum()
{
int sum = 0; // initialize sum
int i;
// Iterate through all elements and add them to sum
for (i = 0; i < arr.length; i++)
sum +=  arr[i];
return sum;
}
// Driver method
public static void main(String[] args)
{
System.out.println("Sum of array is = " + sum());
}
}
```
```numbers = [9, 8, -15, 30, 0]
# start parameter is not provided
numbers_sum = sum(numbers)
print ("Sum of array is = ",numbers_sum)
```
```using System;
using System.Collections.Generic;
using System.Linq;
class LFC
{
static void Main()
{
//
// Declare two collections of int elements.
//
int[] array1 = { 9, 8, -15, 30, 0 };
int sum1 = array1.Sum();
Console.WriteLine("Sum of array is = "+sum1);
}
}
```
```\$a=array(9, 8, -15, 30, 0);
echo "Sum of array is ";
echo array_sum(\$a);
```
```#include <stdio.h>
int main() {
int array[10] = {9, 8, -15, 30, 0};
int sum, loop;
sum = 0;
for(loop = 9; loop >= 0; loop--) {
sum = sum + array[loop];
}
printf("Sum of array is = %d", sum);
return 0;
}
```

#### Output

```Sum of array is = 32
```
