How to quit/exit console app?

[madawg]

#include <QCoreApplication>
#include "MainProcess.h"
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    MainProcess mainProcess;
    mainProcess.process();
    return a.exec();
}

#include <QCoreApplication>
#include "MainProcess.h"
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    MainProcess mainProcess;
    mainProcess.process();
    return a.exec();
}

To copy to clipboard, switch view to plain text mode 

I called

qApp->exit();

qApp->exit();

To copy to clipboard, switch view to plain text mode 

Or

qApp->quit();

qApp->quit();

To copy to clipboard, switch view to plain text mode 

But my console app don't exit.
