  • In the language of C++, a class that is inherited is called a base class. The class that does the inheriting is called a derived class. Therefore, a derived class is a specialized version of a base class. A derived class inherits all of the members defined by the base class and adds its own, unique elements. C++ implements inheritance by allowing one class to incorporate another class into its declaration. This is done by specifying a base class when a derived class is declared. Let’s begin with a short example that illustrates several of the key features of inheritance....

  • This module discusses three features of C++ that directly relate to object-oriented programming: inheritance, virtual functions, and polymorphism. Inheritance is the feature that allows one class to inherit the characteristics of another. Using inheritance, you can create a general class that defines traits common to a set of related items. This class can then be inherited by other, more specific classes, each adding those things that are unique to it. Built on the foundation of inheritance is the virtual function.

  • Natural language generation (NLG) systems are notoriously hard to evaluate. On the one hand, simply comparing system outputs to a gold standard is not appropriate because there can be multiple generated outputs that are equally good, and finding metrics that account for this variability and produce results consistent with human judgments and task performance measures is difficult (Belz and Gatt, 2008; Stent et al., 2005; Foster, 2008). On the other hand, lab-based evaluations with human subjects to assess each aspect of the system’s functionality are expensive and time-consuming. ...

  • The centralization of access to shared services provides a common point of policy enforcement and control for all VPNs. This is referred to as the services edge functional area. Services edge has more of a logical than a physical meaning. In a specific network design, the point of policy enforcement can be physically located in a specific area of the network, but in certain cases, it might also be spread around the network.

  • Writing an extended text at an advanced level involves not just the language system. It poses significant challenges to our cognitive systems for memory and thinking as well. Indeed, writers can put to use virtually everything they have learned and stored away in long-term memory. But they can only do so if their knowledge is accessible, either by rapidly retrieving it from long-term memory or by actively maintaining it in short-term working memory. Thinking is so closely linked to writing, at least in mature adults, that the two are practically twins.
