No, static functions cannot be declared as virtual.

• Virtual functions are used for runtime polymorphism, while static functions are resolved at compile-time.

• Static functions cannot be overridden in derived classes, which is a requirement for virtual functions.

• Declaring a static function as virtual will result in a compilation error.

Yes, user-defined object can be declared as static data member of another class.

• Static data members are shared by all objects of a class.

• User-defined objects can be declared as static data members.

• Example: class A { static B obj; };

• Here, B is a user-defined object declared as a static data member of class A.

Forward referencing is referencing a variable or function before it is declared.

• It is used in programming languages that allow it, such as JavaScript.

• It can be used to create recursive functions.

• It should be used with caution as it can lead to unexpected behavior.

• Example: function foo() { return bar(); } function bar() { return 'hello'; }
