// printSecondBiggest() هنا قمنا بإنشاء مصفوفة أرقام أحادية و تجربة الدالة
int main() {

    int arr[] = { 5, 9, 3, 6, 4, 2, 7, 1, 8 };
    int arrLength = sizeof(arr) / sizeof(arr[0]);

    printSecondBiggest(arr, arrLength);

    char end; std::cin >> end;
    return 0;

}

Second biggest number is: 8
