私がプログラムを実行してプレミアムを選択すると、それが実行され、それから通常のサービスのための機能も実行されます。問題はintのメインラインにあります。私は何を間違えたのですか？ ITは私が問題をはっきりと説明しなかったと言いますが、どうしてここでそれを回避するためのテキストがあるのかわかりません。スイッチとファンクション

どのように、私は問題をリストアップし、私は問題だと思いました。私も完全なコードが含まれています。他には何があるの？ –
補足として、プレミアムサービスを実行するには 'P'と 'p'を、通常のサービスを実行するには 'R'と 'r'を使用すると仮定しています。これは、あなたの望むことですか？あなたが 'r'か 'p'を入力すると今は動作しませんので、すぐに中断して終了します。あなたが望むのは、そのような休憩を取り除くことです。 case 'r'： case 'R'： regserv（）; case 'p'： case 'P'： premserv（daymin、nightmin）; –
