Source File

#include <QFile>
#include <QApplication>
#include <QLabel>
#include <QString>
#include <QTextStream>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QFile file("c://out.txt");
file.open(QIODevice::WriteOnly | QIODevice::Text);
QTextStream out(&file);
out << "This file is generated by Qt \n";
