How to write code in C language instead of QML?

[tom634]

#include "mainwindow.h"
 
#include <QtGui/QApplication>
 
#include <QAccelerometer>
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    MainWindow mainWindow;
    mainWindow.setOrientation(MainWindow::ScreenOrientationAuto);
    mainWindow.showExpanded();
 
    // On the heap (deleted when this object is deleted)
    QAccelerometer *sensor = new QAccelerometer(this);
 
    // On the stack (deleted when the current scope ends)
    QOrientationSensor orient_sensor;
 
    // start the sensor
    QSensor sensor("QAccelerometer");
    sensor.start();
 
    // later
    QSensorReading *reading = sensor.reading();
    qreal x = reading->property("x").value<qreal>();
    qreal y = reading->value(1).value<qreal>();
 
    QAccelerometer sensor;
    sensor.setProperty("maximumReadingCount", 100);
    sensor.setProperty("processAllReadings", true);
 
 
 
    return app.exec();
}

#include "mainwindow.h"

#include <QAccelerometer>

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

    // On the heap (deleted when this object is deleted)
    QAccelerometer *sensor = new QAccelerometer(this);

    // On the stack (deleted when the current scope ends)
    QOrientationSensor orient_sensor;

    sensor.start();

    // later
    QSensorReading *reading = sensor.reading();
    qreal x = reading->property("x").value<qreal>();
    qreal y = reading->value(1).value<qreal>();

    QAccelerometer sensor;
    sensor.setProperty("maximumReadingCount", 100);
    sensor.setProperty("processAllReadings", true);



    return app.exec();
}

With using this code which I written basing on the codes from your site I still receive compilation errors. For example
C:\...\main.cpp:5: error: QAccelerometer: No such file or directory
Or
C:\...\main.cpp:16: error: 'QAccelerometer' was not declared in this scope
or
C:\...\main.cpp:16: error: expected type-specifier before 'QAccelerometer'
How to repair this?
