When employing multiple inheritance, virtual base classes are used to prevent several "instances" of a particular class from appearing in an inheritance hierarchy. Consider the following example: class A { public: void Foo() {} ...READ MORE
Is this class considered abstract because it only contains one virtual function? I could still build an Animal object and use getFoodCost(); No. In C++, a "Abstract Class" is often a class having a single pure virtual function: class Abstract { public: virtual ...READ MORE

Hello, let's say I have an abstract class with a few pure abstract functions and a few classes that derive from it, and all of the data from these classes eventually becomes similar, I was wondering if it would be wise, or even possible, to declare a vector under protected in the abstract class to collect the data so something like that. class A { protected: vector <string> ...READ MORE
An abstract class is one that is intended to be used as a base class . At least one pure virtual function exists in an abstract class. A pure virtual function is declared in the class declaration by using a pure specifier (= 0) in the declaration of a virtual member function. Here is an example of an abstract class: class AB { public: virtual void f() ...READ MORE
