c++ - テンプレートを使用して List と Stack を手動で実装する

Question

私のデータ構造の先生は、リストとスタックを手動で実装するタスクを私たちに与え、それはうまく機能しましたが、テンプレートを使用して任意のタイプのパラメーターを受け入れるように再実装する必要がありました. それ以来、私はさまざまなエラーに直面してきました。現在、c2019 エラーが発生していますが、コードの何が問題なのかわかりません。this: pilha.getTopo<int>();、 this: Lista<int> lista;、 this:typedef Lista<int> Lista_int;を試しましたが、うまくいきませんでした。

今、私のコード：

######更新: 次のコードが機能しています
