program not getting compiled...please help

[sh123]

i checked them both have t1.exe file each

[jpn]

So what's the problem?

[sh123]

the problem is that there is no change in the output .In the code shown below:

#include <QApplication>
//! [1] //! [2]
#include <QPushButton>
//! [2]
 
//! [3]
int main(int argc, char *argv[])
{
//! [3] //! [4]
    QApplication app(argc, argv);
//! [4]
 
//! [5]
    QPushButton hello("Hello qt");
//! [5]
 
//! [6]
    hello.show();
//! [6] //! [7]
    return app.exec();
}

#include <QApplication>
//! [1] //! [2]
#include <QPushButton>
//! [2]

//! [3]
int main(int argc, char *argv[])
{
//! [3] //! [4]
    QApplication app(argc, argv);
//! [4]

//! [5]
    QPushButton hello("Hello qt");
//! [5]

//! [6]
    hello.show();
//! [6] //! [7]
    return app.exec();
}

To copy to clipboard, switch view to plain text mode 

I made following change:

//! [5]
    QPushButton hello("Hello world");
//! [5]

//! [5]
    QPushButton hello("Hello world");
//! [5]

To copy to clipboard, switch view to plain text mode 

but in the output it is showing Hello qt as before even after saving & compiling

Make sure to edit the correct file in the appropriate folder...
