Is that possible to put QSting in to QBytearray?

[victor wang]

Hi All,
I'm using qt5.5 and Linux+QT for my OS system.
This is my program.

QString addr = "55:55:55:55:55:55";
QByteArray pair("pair "+addr+"\n");

Can I just put in like this?
If can't then how can I do something like this?

Thanks in Advanced!

QString addr = "55:55:55:55:55:55";
QBytearray pair = QByteArray("pair ")+addr.toUtf8()+QByteArray("\n");

The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)

Given all your string is ASCII-representable: "pair "+addr.toLatin1()+"\n"

EDIT:
The answer is @raven-worx is also correct, the only note is that I'd use QByteArrayLiteral("pair ") instead of QByteArray("pair ") as some compilers can optimise that better
