while compiling this cpp file getting the compilation error.

C++

class A final
{
public:
    A()
    {
        cout<<"Inside A()"<<endl;
    }

};
/*class B:public A
{
public:
    B()
    {
           cout<<"Inside B()"<<endl;
    }
};*/

int main(int argc, char *argv[])
{
    A obj;
 // QCoreApplication a(argc, argv);
  cout<<"inside main";
  getchar();
  return 0;
  // return a.exec();

}

and my .pro file looks like this
QT += core
QT -= gui

Qt5:
@CONFIG += c++11@

or Qt4:
@CXXFLAGS += -std=c++11@

TARGET = CPP11
CONFIG += console
CONFIG -= app_bundle
TEMPLATE = app
SOURCES += main.cpp

Do you plan to tell us the compilation error?

C2470: 'final' : looks like a function definition, but there is no parameter list; skipping apparent body

OK, so what does that usually mean?

PIEBALDconsult,
I am expecting that it will not give any compilation process....

Remove the '@' characters from your project file:

CONFIG += c++11

When using GCC, check the compilation output window if the C++11 option is passed to the compiler (-std=c++11). When using Visual C++ (which seems to be case according the error code), it must be VS 2012 or later because older versions did not support final.
