表示するにはこの機能を使用できません

Question

私はコーディングが初めてであるため、このコードの一部が厄介で、たぶん理解が難しいと思われます。プログラムは、ユーザーに5つのクラスと各クラスの5つのテストスコアを入力させ、次に関数を使用して、最も低いテストスコア、最も高いテストスコア、および各クラスのスコアの平均を求める必要があります。私はそこでそれぞれの機能を果たしました。次に、別の機能を使用してそれを表示する、私の問題があります。私はそれが簡単な修正だと思いますが、私がする必要があるのは、mainからdisplay関数を呼び出して表示させるだけですが、毎回構文エラーが出ます。私が言ったように、私はそれが簡単な修正になると思うが、わからない。どんな助けもありがとう！

あなたは問題の関数にパラメータを渡すを持って
