This can be in line with the habits of assignment operator for built-in varieties (returning the assigned benefit) and permits utilizing the operator invocation as an expression, for instance on top of things statements or in chained assignment.
If your style and design wants virtual dispatch into a derived class from the base course constructor or destructor for features like file and g, you'll need other methods, like a submit-constructor – a different member function the caller ought to invoke to finish initialization, which could safely get in touch with f and g mainly because in member functions Digital phone calls behave Typically. Some approaches for this are proven within the References. Listed here’s a non-exhaustive list of selections:
