私はプログラミングのノブです。この電卓を正しく動作させることができません。私はすでにすべてのボタンをコーディングしており、キーボードからの入力を許可しています（これは無関係なのでコード抜粋に入れませんでしたが）。タイトルから分かるように、等価ボタンは複数の合計で機能しません。私は何が問題を引き起こしているのか分かりません。任意の提案をいただければ幸いです。シンプルな計算機の問題（同等のボタンを2回以上動かすことはできません）
ここに私のコードです。

double result = 0.0; //calculated result
bool operationCompleted = false;

私はそれがあなたの 'operation'変数に関係していると思います。あなたは 'char'と宣言しますが、演算子ボタンを押すたびにその状態を「破損」させます。 '+ ='の代わりに '='を使うか、計算の間にクリアするべきです。 –
