Question
Which of the following is CORRECT about static methods of a class?You can also declare a member function as staticSuch functions can access only static variablesThe static functions exist even before the object is createdAll of the above
Solution
All of the above is correct about static methods of a class.
-
You can declare a member function as static: In many programming languages like Java and C++, you can declare a member function or method as static. This means that you can call the method without creating an instance of the class.
-
Such functions can access only static variables: Static methods can only directly access static variables and other static methods. They cannot directly access instance variables or instance methods, because they do not belong to any instance of the class.
-
The static functions exist even before the object is created: Static methods are part of the class, not part of the object. They exist as soon as the class is loaded into the memory, which is before any objects of the class are created.
