Function returns a gibberish value

[ayanda83]

Hi everyone, I have the function below. the function is suppose to generate an account number and return it in form of a QString.
QString NewAccount::genAccountNum()
{
QString tempStr, accNum;

int num1 = rand()%100000 + 999999;
tempStr.append(static_cast<QString>(num1));
accNum.append("AB");
accNum.append(tempStr);

return accNum;
}


The function returns the substring "AB" followed by gibberish, something that looks like Chinese fonts. AM I DOING SOMETHING WRONG HERE?

I would use:
tempStr.append(QString::number(num1));

As sulliwk06 says the function you want is QString::number() or QString::arg(). There is no meaningful way to cast an int to QString, so when you forced the compiler to do it anyway what you ended up with was something that will sometimes give rubbish and sometimes crash your program.
