How to print Qdate value on screen

[RDiGuida]

Hello, I am very new to Qt and I bumped into a problem that might well be stupid as far as I know. In the following chunk of code

QFile file("bds.txt");
QTextStream in(&file);
if (!file.open(QIODevice::ReadOnly | QIODevice::Text))
       return 1;

QString discard,dateStr;
QList<QDate> dates;

while(!in.atEnd())
{
    in >> discard;
    in >> dateStr;
    dates.append(QDate::fromString(dateStr,"d'/'MMM'/'yyyy"));
}

QString dt ((dates[0]).toString());
std::cout << dt << std::endl;

I obtain the following error

    error: no match for 'operator<<' (operand types are 'std::ostream {aka std::basic_ostream<char>}' and 'QString') std::cout << dt << std::endl;

So I created a TextStream as follows

QTextStream outt(stdout);
 ....
 ....
outt << dt << std::endl;

Obtaining the following error

error: no match for 'operator<<' (operand types are 'QTextStream' and '<unresolved overloaded function type>') outt << dt << std::endl;

How can I overcome this problem and why am I having this problem in first place?

I think this one should work:

std::cout << dt.toStdString() << std::endl;

@RDiGuida To add to @Mario84's answer, QString is Qt based class and your using standard c++ API's to print it which it doesnot understand. To print values of pure Qt based API's you can use qDebug().
Eg:

QString dt ((dates[0]).toString());
qDebug() << dt;
