How to add constructors/destructors to an unnamed class?

Question

Is there a way to declare a constructor or a destructor in an unnamed class? Consider the following

void f()
{
    struct {
        // some implementation
          


        

Answer 1

You can not declare a constructor or destructor for an unnamed class because the constructor and destructor names need to match the class name. In your example, the unnamed class is local. It has no linkage so neither mangled name is created.
