ソフトウェアエンジニアリングペアリング課題 02
1. 設計アイデア:
このタスクの主要な関数を実装するには、デフォルトでは加算と減算が必要です。含まれること。 まず、index.php
ファイルを作成し、HTML ステートメントでフォームを作成します。質問の数、最大値と最小値、その他のオプションが含まれます。 次に、rubric.php
ファイルを作成し、このファイルにフォーム情報を送信し、四則演算メソッドの実装時に渡された値を呼び出します。四則演算の実装方法は、以前に何度か Java を使用したときに使用した方法と同様であり、コードが修正および最適化されています。後で使用できるように、質問と回答をそれぞれ question.txt ファイルと answer.txt ファイルに保存します。 3 番目に、submitAnswer.php
、acceptAnswer.php、deleteAnswer php を作成します。 および judgeAnswer.php ファイルは、それぞれオンラインでの回答の送信、回答の受信、回答の削除、および回答の判断に使用されます。送信された回答は、answer1.txt ファイルに配置されます。回答は、answer.txt と answer1.txt ファイルの内容で十分です。 2. ソースプログラムコード
