[raphaelf]

Hello everybody,

I have some numbers, for example 16, 20, 23, 40, 43

I need to generate a random number of only this numbers i have.

How could i make this on QT or C++ ??

Can somebody help me?


For the moment i have this:

int max;
	QSqlQuery count("select count(words_id) from words_tbl");
	while(count.next())
	{
		max = count.value(0).toInt();
	}
 
	//random
	int a = (1 + ( rand() % ( max - 1 + 1 ) )); 
	QString b = QString::number(a);

int max;
	QSqlQuery count("select count(words_id) from words_tbl");
	while(count.next())
	{
		max = count.value(0).toInt();
	}
	
	//random
	int a = (1 + ( rand() % ( max - 1 + 1 ) )); 
	QString b = QString::number(a);
