所以我有學校項目，我創建這個作爲頭文件在c + +。但我編譯這個錯誤來了「錯誤C3861：'load_now'：標識符未找到第92行」。我不明白爲什麼以及如何解決它。在一個類中找不到標識C++

'Load_now'。 – songyuanyao

你在你的代碼稍有問題。您有Load_now。所以，

return load_now(seq->get_data(inp));

VS`load_now`替代由

return Load_now(seq->get_data(inp));

什麼是seq->get_data(inp)返回？我認爲編譯器不確定seq->get_data(inp)的數據類型。

而且Load_now不load_now
