In multilevel inheritance, a class is derived from another derived class. This inheritance can have as many levels as long as our implementation doesn’t go wayward. In the above diagram, class C is derived from Class B. Class B is in turn derived from Class A. Let us see an example ...
The article considers using multiple inheritance in C++ programs. A single inheritance with various classes is provided to elaborate the conversion of a pointer to an object into a pointer to its public inheritance base. In this single inheritance, the vptr points to the vtable of the actual ...
When different classes implement the same-named method, a program can better use polymorphism in its design. 8. Easy to bring changes: Library code reused in our programs keeps on constantly improving by the libraries’ developers. So, the benefits of these improvements can be made in your ...
Kindly explain "What is the use of Inheritance? and When to use?" with respect two below programs. Why I cannot get output from 1st program after using class initialization? Program 1: classProgram { classShape { publicvoidsetWidth(intw) { width = w; } publicvoidsetHeight(inth) { heig...
In this tutorial, we will learn what C# Inheritance is, how to implement Inheritance in C# programming, and some of the implementations with example programs.

In general, it is not allowed to call the grandparent’s constructor directly, it has to be called through parent class. It is allowed only when ‘virtual’ keyword is used. As an exercise, predict the output of following programs.
