In this program, You will learn how to find the sum of array elements using the function in C++.

```
Sum of array elements using the function
sumOfArray(arr, size);
```

## Example: How to find the sum of array elements using the function in C++.

```
#include<iostream>
using namespace std;
void sumOfArray(int arr[], int n) {
int s = 0;
for (int i = 0; i < n; i++) {
s = s + arr[i];
}
cout << "Sum of array elements:" << s;
}
int main() {
int arr[10], i, n;
cout << "Enter size of an array:";
cin>>n;
cout << "Enter array elements:";
for (i = 0; i < n; i++) {
cin >> arr[i];
}
sumOfArray(arr, n);
return 0;
}
```

#### Output:

```
Enter size of an array:5
Enter array elements:10 20 30 40 50
Sum of array elements:150
```
