What is polymorphism? Be sure to include what role virtual functions play in this and the difference between a virtual and pure virtual function. Be sure to include the defininition of an abstract base class.
Create a simple “Car” hierarchy in C++: a base class called Car and derived classes called Toyota, Honda, and Mazda. In the base class, make a virtual function called start( ), and override this in the derived classes. Make a pointer of Car and objects of derived class and call start( ) through the base-class pointers, to verify the behavior of the virtual function.
Tell whether or not the following statement is accurate:Only pointers and references are permissible for dynamically bound virtual functions.
solve using oop in c++ Define the base class Base, whose data members are high h, and define the member function disp() as a virtual function. Then, the base class derives the cuboid class Cuboid and the cylinder class Cylinder. And define the member function disp() as a virtual function in the two derived classes. In the main function, use the base class Base to define the pointer variable pc, and then use the pointer pc to dynamically call the base class and The virtual function disp() in the derived class shows the volume of the cuboid and cylinder.
How should a software call a base class virtual function so that it may make use of the same virtual function in a variety of different forms and structures? A base class pointer or reference is required.
By using pure virtual functions, create a simple “shape” hierarchy in C++: a base class called Shape and derived classes called Circle, Square, and Triangle. In the base class, make a virtual function called draw( ), and override this in the derived classes. Make a pointer of Shape and objects of derived class and call draw( ) through the base-class pointers, to verify the behavior of the virtual function.
Write a program in c++ to create a base class: “Question3”, with protected data member: x (int) and with pure virtual function: “Task ()” [Returns no value and takes no argument]. Create a derived class of “Question3” such as “Sub1” (Derive features in public mode). In sub1, there is a member function in public section: get_data1 () to take input for x, and define Task () in this class to display the reverse of x. [Implement the above program by creating pointer to base in main () function and call the necessary functions.
How should a software utilize pointers or references from the base class to invoke the same virtual function so that it may be used in different data types?
C++ Discuss the context where it becomes important to make base class virtual. Also include an appropriate example.
What is Pure Virtual Functions?By using Pure Virtual Functions, create a simple “shape” hierarchy: a base class called Shape and derived classes called Circle, Square, and Triangle.
