Get first name and last name out of a full name QString

Question

I have a QT Project where I get the full name as a QString variable fullName from user input. I'd like to store the first name ( firstName ) and last name ( surname ) in their own QString variables by extracting them from fullName .

The user input could end up adding their middle names as well so I need to to work for all kind of examples like that, eg. user input: Barry Michael Doyle would have to give firstName the value of Barry and surname the value of Doyle .

I'm not very good at QString Manipulation as I've only recently started using the Qt Library. I'd appreciate all the help I could get.

Qt's documentation on QString is pretty thorough and has a lot of examples on how to use it. You can find it here: http://doc.qt.io/qt-5/qstring.html

In general, parsing an input string that could have mistakes in it is difficult (what would the expected behavior of an input string of "BarryDoyle" be? What about "Barrydoy le"?)

For the simple case of splitting a string using the space character you can take a look at QString::split ( http://doc.qt.io/qt-5/qstring.html#split )

QString str = "Barry Michael Boyle"
QStringList list_str = str.split(" ");
QString first = list_str.first();
QString last = list_str.back();
