File: override_error.cpp


When a virtual method print() in Class A is declared as final and when
inherited in the Class B, overriding this method is not generating a
compilation error. 


g++ -std=c++11 override_error.cpp


File: overrride.cpp

When virtual method print() in Class A is defined within the class and when
inherited in the Class B, overriding this method is  generating a compilation
error as expected.

g++ -std=c++11 override.cpp
verride.cpp:29:15: error: virtual function 'virtual void B::printVal()'
         void  printVal() override;
               ^
override.cpp:13:22: error: overriding final function 'virtual void
A::printVal()'
         virtual void printVal() final
