How do I filter or output within an array if the number I searched for was not found?

I cannot output correctly when the number is not found in the array. I've tried multiple conditionals so it would only trigger when it is true. But nothing worked.

int main()
{
    int abfrage;

    cout << "Type a number between 0 and 1000 to find it's position in the array " << endl;
    cin >> abfrage;
    const int feld = 1001;
    int zahlenfeld[feld];
    int i = 0;

    for (int i = 0; i < feld; i++)
    {
        zahlenfeld[i] = rand() % 1001;

        if (zahlenfeld[i] == abfrage)
        {
            cout << "Your number" << abfrage << " " << "is at the position" << i << endl;
        }
        else if (cin.fail() || abfrage > 1000 || abfrage < 0)
        {
            cout << "Wrong input. Only positive integers are possible." << endl;
            break;
        }
        else if (zahlenfeld[i] != abfrage)
        {
            cout << "The number you searched for is not in the array." << endl;
            break;
        }
    }
}
