No. Virtual functions are invoked according to the runtime type of the object. That is; the most-derived override is automatically invoked even when the runtime type of the object cannot be determined at compile time. This is achieved through the object's virtual table. Static methods do not have any object associated with them; they can be invoked even when no object of the type exists. Without an object, there can be no virtual table. Thus static functions cannot be virtual. They are mutually exclusive concepts.

What types of functions cannot be made virtual?
Static member functions, member function templates and constructors cannot be virtual.
What is the function of static relay?
function of static relay
What is the difference between static function and global static function?
'global static'?! There is no such thing.
A pure virtual function is a virtual function that has?
A pure-virtual function is a function that must be overridden in derived classes. You simply add "=0" to the end of the function declaration. class AbstractClass { public: virtual void DoSomething()=0; // Pure-virtual. };
What is the difference between virtual function and function overriding?
Virtual Functions and Pure Virtual Functions are relevant in the context of class inheritance.Unlike Virtual Functions, Pure Virtual Functions do not require a body. This implies that when a base class defining such a function is inherited, the derived class must implement that function. Furthermore, the base class becomes abstract; meaning you cannot create an instance of the base class even if a body is implemented for the function. You are expected to derive from abstract classes; only the derived classes that implement all the inherited Pure Virtual functions can be instantiated.Here are some examples of Virtual and Pure Virtual function signatures:- Virtual Function: E.g. virtual void myFunction();- Pure Virtual Function: E.g. virtual void myFunction() = 0;

What is the Use of static function?
A static function is a member function that is not associated with any instance of the class; it has no this pointer.
What is virtual function table?
A virtual function table is a table of pointers to functions.
How do you create static variables in PHP?
Use the "static" keyword to declare a static variable within a function like shown below. <?php function fun() { static $variable; static $another_variable = ''; } ?>
Scope of static variables?
Scope of static variable is with in the file if it is static global. Scope of static variable is with in the function if variable is declared local to a function. But the life time is throughout the program
When Static function can work with static data member only?
Always.
Can static member function be overloaded?
Yes. Any function can be overloaded. However you cannot override a static member function. Only instance members can be overridden.
