Warning message

room.cpp:1: In file included from ..\room.cpp:1:0:
room.h:-1: In constructor 'Room::Room(const QString&, const QString&, const QString&, int, QWidget*)':
room.h:28: warning: 'Room::roomId' will be initialized after [-Wreorder]
     const QString roomId;
                   ^
room.h:26: warning:   'QString Room::sleepPrice' [-Wreorder]
     QString sleepPrice;
             ^
room.cpp:12: warning:   when initialized here [-Wreorder]
 Room::Room(const QString &_roomId , const QString &_takePrice ,
 ^

My source generates the above warning message.
It works well.
Why is that message coming up?
How do I resolve it?

I thank you in advance for your advice.

Hi,

This warning simply say that you must initialize your variables in the same order that they are declared.
