你好,我剛剛開始使用C++ MySQL連接的器件的應用 發佈| WIN3MySQL連接/ C++的示例代碼是不工作

你可以正確縮進你的代碼嗎?我不想浪費我的志願時間精神上跟蹤示波器。 – 2012-04-13 10:31:03
此代碼來自http://dev.mysql.com/doc/refman/5.1/en/connector-cpp-examples-complete-example-1.html我不確定是否依賴y庫。這是我的樹http://www.wgraj.org/uploads/photos/simple/screen_6adc371c220e99f428fd221552609358.JPG – 2012-04-13 10:37:19
你爲什麼要給我看你的項目樹?我在談論正確縮進代碼。由於SO不是付費支持網站,因此讓您的問題可讀性最低。 – 2012-04-13 10:42:34
