I made a simple console app which accepts a user’s name and prints it.

It does not work as expected. Here is the code:

#include <QCoreApplication>
#include <QTextStream>

void do_qt()
{
    QTextStream qin(stdin);
    QTextStream qout(stdout);
    qout << "Enter your name: ";
    QString name = qin.readLine();
    qout << "Hello " + name + "n";
}

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    do_qt();
    return a.exec();
}

This is the output
