爲什麼.................... printf？ – LogicStuff

那麼，今天學到了一些新東西。在字符串中使用printf時存在未定義的行爲，並且您可能爲缺少的大小寫塊（6,7,8等）插入值。改用std :: cout。 – 2016-11-24 19:56:14

顯然，用cout作品取代了所有的印刷品。但爲什麼？你能不能將cin/cout與scanf/printf混合？下面的工作正確。 cout <<「Player name：」<< playername << endl; cout <<「Position：」<< position << endl; \t cout <<「Height：」<< height <<「Weight：」<< weight << endl; <<「家鄉：」<<故鄉<< endl; cout <<「Class：」<< Class << endl; – Rabbit84

查看其他帖子鏈接後，printf顯然會工作，如果你使用printf（「Follow this command：％s」，myString.c_str（））; 。 .c_str（）允許以我最初嘗試的方式使用它。感謝您的幫助和鏈接。不知怎的，我錯過了那篇文章。 :)
