multiple inheritance c++
Should a class inherit from a single or multiple class?
What is most important when doing any form of public inheritance (single or multiple) is to respect the is a relationship. A class should only inherit from one or more classes if it "is" one of those objects. If it simply "contains" one of those objects, aggregation or composition should be used instead.
What is multiple inheritance in C++?
Multiple Inheritance is a feature of C++ where a class can inherit from more than one classes. The constructors of inherited classes are called in the same order in which they are inherited. For example, in the following program, B’s constructor is called before A’s constructor. A class can be derived from more than one base class.
Why is multiple inheritance a problem?
Multiple inheritance has been a controversial issue for many years, with opponents pointing to its increased complexity and ambiguity in situations such as the "diamond problem", where it may be ambiguous as to which parent class a particular feature is inherited from if more than one parent class implements said feature.
What is a good example of multiple inheritance?
Most uses of full scale Multiple inheritance are for mixins. As an example: class DraggableWindow : Window, Draggable { } class SkinnableWindow : Window, Skinnable { } class DraggableSkinnableWindow : Window, Draggable, Skinnable { } etc... In most cases, it's best to use multiple inheritance to do strictly interface inheritance.
C++ Multilevel Inheritance
In C++ programming, not only you can derive a class from the base class but you can also derive a class from the derived class. This form of inheritance is known as multilevel inheritance. Here, class B is derived from the base class A and the class C is derived from the derived class B. programiz.com
C++ Multiple Inheritance
In C++ programming, a class can be derived from more than one parent. For example, A class Bat is derived from base classes Mammal and WingedAnimal. It makes sense because bat is a mammal as well as a winged animal. programiz.com
C++ Hierarchical Inheritance
If more than one class is inherited from the base class, it's known as hierarchical inheritance. In hierarchical inheritance, all features that are common in child classes are included in the base class. For example, Physics, Chemistry, Biology are derived from Science class. Similarly, Dog, Cat, Horse are derived from Animal class. programiz.com
