更新： 私はプログラムをコンパイルして実行することができました。しかし、ジャッジスコア値2.3の変数は、奇妙な方法で格納され、計算をスローしています。私は2.3を入力すると、ストアの値は2.299999999998です - これはなぜですか？スコアを入力すると最終スコアが0.3になるため、calcScoreまたは最低および最高の関数がエラーになることがあります。2.3 - 5.5 - 5.5 - 5.5 - 8.5 - 任意のアイデア？C++エラー： 'int'の前にprimary-expressionが必要ですか？

ORIGINAL：
私はちょうど5点の得点を平均と最低を削除する方法を考え出すと最高カント私の代数式が整数3で書かれているライン39上のコンパイラエラーを取得しています。最高と最低を決定する関数は順番になっているようですが..助けてください。
ありがとうございます。

なぜ表現の途中に 'int findLowest（...）'がありますか？ – tpg2114
は答えませんでしたが、最後に '}'を '}' –
に置き換えたいと思うかもしれませんが、実際のコードではないと私は思っています。ありがとう！ – user1278971
