Simple Array Sum

Ruby

n = gets.strip.to_i
arr = gets.strip
arr = arr.split(' ').map(&:to_i)
total = 0
arr.each {|num| total += num}
puts total

C

int main(){
    int n, total; 
    scanf("%d",&n);
    int arr[n];
    for(int i = 0; i < n; i++){
       scanf("%d",&arr[i]);
    }
    for (int i = 0; i < n; i++){
        total += arr[i];
    }
    printf("%d", total);
    return 0;
}
