Pure Virtual Destructor with Default Keyword

Question

Is it possible to declare a destructor as pure virtual and use the default keyword? For example, I can't seem to make code like this work:

class MyClass
{
public:
  // Is there a way to combine pure virtual and default?
  virtual ~ MyClass() = 0,default;
};

One can of course later do:

MyClass::~ MyClass() = default;

Also, if the destructor is not pure virtual, the default keyword does work when it follows the declaration.

Right, thanks. The standard indeed says > a function declaration cannot provide both a pure-specifier and a definition — Christopher Johnson
default a virtual destuctor ... What for ? It's virtual so defaulting it won't make it trivial and nothing changes for your class from defining it as { } — Nikos Athanasiou

No.

You will have to write a separate definition and default it there, as you've shown.

The presence of a pure-specifier precludes the presence of a definition at the same location, even when that definition is just a = default.
