私はこのサイトをかなり新しくしていて、私の強い訴訟ではなくプログラミングしています。以下は、私が宝くじスクラッチャーをすることから利益を上げる確率を計算するために書いたコードです。結果を.txtファイルに出力すると仮定します。私はそれをそのファイルに出力することができます。出力ファイルのすべては、2番目のゲームの名前を除いて正しいものです。それは完全な言葉がありません。私の出力ファイルの外観は以下の通りです。出力ファイルにプログラムが正しく出力されていない
Game Cost Odds
-----------------------------------------------
SMALL BEANS $ 1 1 in 1.67
BOOTY, ARRR $ 10 Not possible
MONEY HU$TLA$ $ 20 1 in 99.80
第2ゲームと第3ゲームの両方には、開始前に空き領域があり、理由はわかりません。また、2番目のゲームは、 "海賊の戦利品、Arrr。どのように言葉が欠けているのか分かりません。これを修正する方法についての助けは非常に高く評価されるでしょう。私のコードは以下の通りです。
