Create a random string or number in Qt4

Question

Is there any function or something like that by which I can create totally random strings or numbers?

Answer 1

int number;
int randomValue = qrand() % number;

returns a random number randomValue with 0 <= randomValue < number.

qrand() is declared in QtGlobal which is #included by many other Qt files.

int value;
QString aString = QString::number(value);

converts an integer to QString.
