In a game, bonuses are doubles but score is int:


class ScoreKeeper {

  public static int applyBonus(int score, double bonus) {

    int total = score + (int) bonus; // truncates decimals

    return total;

  }

}

Based on the code above, what will be the result of casting the variable bonus from double to int?

A game clamps score after adding a bonus:

`class ScoreKeeper { public static int safeAdd(int score, double bonus) { int added = (int) bonus; // may be large int total = score + added; // overflow risk return total; } }`

Which line of code will cause a problem due to range limitations?
