Calling a Virtual Function From a Constructor? Bad Idea!

In this video, we are investigating the issues that can exist in a class where its constructor is making a call to a virtual method - specifically, the method that is overridden in the derived class.
After discovering a bug, and even making a couple of half-baked attempts to solve it, we are moving to a general solution to the problem. By the means of object-oriented design, and accepting that the constructor cannot use object's state for its purpose (it is the constructor the one to construct that state!), you will learn the coding technique where data are passed safely between constructors, removing any need for calling virtual methods at that stage.
