Hackerrank Simple Array Sum (C++)

C++ :

int simpleArraySum(vector<int> ar) {
     * Write your code here.
    int sum = 0;
    for(int i = 0; i < ar.size(); i++){
        sum += ar[i];

    return sum;


Missed this all the way till the last warmup challenge. This is simple, simply adding up all the elements of a vector in sum, then returning it. Nothing much to say here, really.
