The static member function indirectly accesses non-static data members.

// The static member function indirectly accesses non-static data members.
// Static member functions can directly reference static data members and static member functions of the class, but cannot
// Directly reference non-static data members and non-static member functions; otherwise, an error is returned during compilation.
// If You Want To reference an object, you must pass the parameter to obtain the object name, and then use the object name to reference it.
