According to the rule of static in C++, only static member function can access static data members. Non-static data member can never be accessed through static member functions. Note: Inline function can never be static.C++ - Static Data Member C++ - Static Data Member Example ...

Since a static method cannot access class attributes, it can be used as a utility function to perform frequently re-used tasks. We can invoke this method using the class name. Hence, it eliminates the dependency on the instances. A static method is always predictable as its behavior remain ...
