cout in Qt

[qt_developer]

Hi all,

I want to use cout in Qt. I have this code:

#include <QtGui/QApplication>
#include <iostream>
 
using namespace std;
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
 
    cout << "finish";
    return a.exec();
}

#include <QtGui/QApplication>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    cout << "finish";
    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

but the text "finish" doesn't appear.

What's wrong?

Regards.

Do you have CONFIG += console in your .pro file? Tell us more about what is happening: what os are you using? the console/terminal doesn't appear? or it appears without output?

And why are you using a QApplication and it's exec()? Do you really need that, because it create an event loop that you will want to close (by connecting a signal to it's quit slot)

No, I have added CONFIG += console in my .pro file and now I can see the output, but when the application is closed. I'm using MS Windows. I have run the project from Qt Creator and I expected see the output in "Application output".

No, I have created an empty project by "Qt Gui Application" and QApplication and it's exec() appear by default. What's the best way to create a console project?

Regards!

Add " << endl".
