If your style and design wishes virtual dispatch right into a derived course from the foundation class constructor or destructor for features like f and g, you require other techniques, like a write-up-constructor – a independent member perform the caller ought to invoke to accomplish initialization, that may safely and securely simply call file and g because in member capabilities virtual calls behave Generally. Some tactics for this are shown in the References. In this article’s a non-exhaustive listing of options:
Nevertheless, when There's two ways of expressing an concept and one has revealed itself a typical source of glitches and the other has not, we endeavor to guide programmers to the latter.
