質問が毎回ランダム化され、ユーザーのさまざまな応答 (正解、不正解、合格) が記録されてクイズの最後に表示されるクイズを Bash で実装する適切な方法はありますか?
クイズの質問と回答を保存するために配列を使用し、クイズの質問自体を while または until ループ内で尋ね、最後の質問に到達するまでさまざまな質問を増やし、さまざまな条件文を使用してユーザーのパフォーマンスを評価できると思いますか?
その点に注意してくださいこの古い疑問グラフィカルなクイズ ソフトウェアについて説明し、サウンドやグラフィックスなどについて明示的に言及しましたが、私はコマンド ラインのテキストベースのクイズについてのみ話しています。
(私は自分の質問に下記で回答しました...ただし、Bash でクイズを作成するための別のフレームワークをお持ちの方は、投稿してください。)
答え1
私が考案したクイズのフレームワークは以下に掲載されています。また、GitHub(元のユーザーの GitHub ページはもう存在しません)。
かなり複雑そうに見えるので、どのように動作するかを少し説明したほうがよいでしょう。
スクリプトでは、これまでのすべてのリリースのUbuntuのバージョンとコード名が2つの配列に保存されています。変数は初期化されます。外until ループの、C スタイルの表記法を使用してループ内で必要に応じて増分できる変数です(( var++ ))。
次に、質問番号用の別の配列を作成します。この場合、19 個の質問には 0 から 18 までを含める必要があります。
questions_order=(15 4 1 10 8 3 13 0 11 16 2 7 5 17 6 9 14 18 12)
次に、それを使用してシャッフルしshuf、新しい配列を作成し、それをスクリプトのこの特定の実行に使用します。
shuffled_order=( $(shuf -n19 -e ${questions_order[@]}) )
これはやらなければならない外ループは 1 回だけ実行したいので、省略します。
つまり、現在の質問数が変数と等しくなるまでループが実行され"${target_questions}"、その後結果が表示されます。
ユーザーが質問に回答すると、その回答はステートメント内のさまざまな条件によって解釈されますcase。無回答 (空白)、誤回答、正解、合格はすべて検出され、応答を受け取り、さまざまな変数がすべて増加します (例: 誤回答の場合、(( wrong++ )))。
最後の質問への回答が完了すると、ユーザーのパフォーマンスが評価され、正解数、不正解数、合格数（ある場合）が伝えられ、かかった時間も表示されます。
これは簡単な説明ですが、スクリプト自体にはさまざまなコメントがあり、動作が(ほぼ)明確になるはずです。首都や国に関する他の種類のクイズにも適応できます。
スクリプトをファイルにコピーしたら、それを実行可能ファイル ( chmod u+x) にして、 で実行する./scriptnameか、 フォルダーに配置して~/bin、他のプログラムと同様に名前で呼び出します ( が~/binにあると仮定PATH)。
