LKBEN11614: How to generate a random number between two boundaries in C++ with Qt.
Symptom
You need a good random number with a low and a high boundary.
Cause
-
Solution
You will need to include the headerfile QRandomGenerator64.
Please note, this is not a complete example and it will not compile on its own!
#include <QRandomGenerator64>
...
//generate a random number between 1000 and 9999
quint32 challenge = QRandomGenerator::global()->bounded(1000, 9999);
...
//show the random number in a edit field
ui->lineEditChallenge->setText(QString::number(challenge));
Have fun.
