virtual and inline are function specifier.
They can appear before function only.{as per my understanding}.
Then,In following code what is virtual?
class Base
{
//
};
class Derived :virtual public Base
{
};
If your question is about the wording in the standard, then you must have misunderstood it. It is true that the list of various function specifiers includes the keyword
virtualas one possible function specifier. However, it doesn’t work in other direction: the keywordvirtualis not restricted to being the function specifier only. It has other use(s). You have found an example of that – it can be used to declare virtual base classes.
