Create a random string or number in Qt4

Creating a random string on qt4:

         By creating the  random numbers  by using qrand and  convert  into the string and the QUuid class  Universally Uniqand to generates the unique Identifiers. It is unique but they are totally random.

The following code is given below:

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

By returning a random number randomValue with 0 <= randomValue < number.

   qrand() is stated in QtGlobal   in  #included by  all  other Qt files.

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

convert by integer into Qstring.

The simple statement is:

To  generate the  alphabetic strings and  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;
}
