Can there be anything between keyword 'class' and class name in c++?

Question

I encountered a code in c++ where class has been defined like :

class MACRO class_name
{
     public :

     private :

}

Answer 1

In standard C++11 and later, there can be attributes between class and the class name. It is also possible (even more likely, perhaps) that the macro expands to non-standard attribute syntax supported by the particular compiler that is being used to compile the code.
