どうぞよろしくお願いいたします。
以下は、宿題のために提出しようとしている簡単なプログラミングの割り当てです... プログラムの 65 行目と 69 行目に 2 つの関数を書きました * 1 行前にコメントでマークされ、関数は 93 行目で定義されています101 および 103-111 *1 行先にコメントを付けてマークすることもできます。プログラムを実行すると、「最大降雨量」と「最小降雨量」の値 0 が返され、月 (インデックス) の値は提供されません。それが降った月で最大の降雨量とそれが発生した月で最小の降雨量を表示することが私の目標です...これに正しく近づいていますか?
いつもありがとう。
