Console application - exit application and order of code

[Tomasz]

Hello!

I've got simple console application and I've got some questions.

#include <QtCore/QCoreApplication>
#include <QTextStream>
 
QString temp;
 
int main(int argc, char *argv[])
{
    QTextStream out(stdout);
    temp = "test";
 
    QCoreApplication a(argc, argv);
 
    out << temp << endl;
 
    return a.exec();
}

#include <QtCore/QCoreApplication>
#include <QTextStream>

QString temp;

int main(int argc, char *argv[])
{
    QTextStream out(stdout);
    temp = "test";

    QCoreApplication a(argc, argv);

    out << temp << endl;

    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

First - is the order of code correct? Where should be "QCoreApplication a(argc, argv);"? As i assume "return a.exec();" should be at the end?
What about exiting the application? When I run it in console, it works all the time - don't exits.

thanks in advance
best regards
