問題：
I'm using Qt4 and C++ for making some programs in computer graphics.我正在使用 Qt4 和 C++ 來製作一些計算機圖形程序。 I need to be able to print some variables in my console at run-time, not debugging, but cout doesn't seem to work even if I add the libraries.我需要能夠在運行時在我的控制檯中打印一些變量，而不是調試，但是即使我添加了庫， cout似乎也不起作用。 Is there a way to do this?有沒有辦法做到這一點？
