Questions like these which you can easily check by running it should be asked after you've tried it yourself. Make it a habit of testing things yourself first. Make your own conclusions and come here (with your the test code) to verify it, don't be lazy.

See this class MyClass { static int a = 0; int b = 2; public: static int staticfn() { return a+b; } }; This code is wrong. Why? Because the static member function is not called through an instance. It's done this way instead: MyClass::staticfn(); but then if called this way, what is b? How can the function know about b if we aren't calling it through an instance?

Member variable is accessible when the class is initialized. A static function could be called without class initialization.

A static function is one, that is only available within in translation unit. The static of the function have nothing to with the static storage class. If you are using C++, then you have additionally static function within classes, which means for them to be accessible without an object of that class.
