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

The following example generates alphabetic strings with capital letters from A to Z and length = len.

QString randString(int len)
{
    QString str;
    str.resize(len);
    for (int s = 0; s < len ; ++s)
        str[s] = QChar('A' + char(qrand() % ('Z' - 'A')));

    return str;
}
