A virtual function is a member function in the base class that we expect to redefine in derived classes. In this tutorial, we will learn about the C++ virtual function and function overriding with the help of examples.
Let's assume the following simple class hierarchy with classesA,BandCfor the discussions in this text.Ais the super- or base class,Bis derived fromAandCis derived from classB. In some of the easier examples, we will only refer to a part of this class hierarchy. Inherited Methods A method...
Too Long; Didn't Read Method overloading and overriding are two common forms of polymorphism in C# that are often confused because of their similar sounding names. In this article, we show the difference between the two with some practical code examples. Overloading is the ability to have ...
As we have seen in the above examples, method overriding is achieved by using both abstract and virtual keywords. Some key points to be remembered for implementing method overriding are:The overridden method should always be declared as abstract, virtual or override in the base class. The non-...
Types of Overriding in C# with Examples, Override – This keyword is used with a derived class which signifies that derived class overrides a method of a base class. public override void Method() {// implementation} 3. Base – This keyword is used in a derived class to call the base cla...
