Program to find sum of elements in a given array

Given an array of integers, find sum of its elements.

/*  Program to find sum of elements

 in a given array */

#include <bits/stdc++.h>

// function to return sum of elements

// in an array of size n

int sum(int arr[], int n)

{

    int sum = 0; // initialize sum

    // Iterate through all elements

    // and add them to sum

    for (int i = 0; i < n; i++)

    sum += arr[i];

    return sum;

}

int main()

{

    int arr[] = {12, 3, 4, 15};

    int n = sizeof(arr) / sizeof(arr[0]);

    printf("Sum of given array is %d", sum(arr, n));

    return 0;

}

Output:

Sum of given array is 34
