- With appropriate examples, explain the features of static class members.Examine the role of access keywords in defining class members.In C++, create a three-level hierarchy of classes with default constructors, along with destructors, both of which announce themselves to cout. Verify that for an object of the most derived type, all three constructors and destructors are automatically called. Explain the order in which the calls are made.
- 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.What is the role of abstract classes and interfaces in achieving polymorphism?a) What is Polymorphism? Explain its relation to Inheritance and Generic Programming.b) What is the difference between Dynamic Binding and Static Binding? Provide an exampleof each.c) What is the protected modifier?d) What is the final modifier?
- For this problem you are to join the following classes into a hierarchy (use the UML diagrams from Module 2 to get started): Pet - Super Class Dog - Subclass Cat - Subclass Monkey - Subclasswrite a class implementation using C++ from the given class diagram TAKE NOTEOF THE FF SPECIFICATIONS: Using the constructor, create three objects from class Voters and store it in the stack memory. Two voters must have an active account and one voter has a deactivated account. Please note that the deactivated voter account must be still part of the “object”. Test all the functions by making calls. this should be the sample result. Please use simple codes only.Explain why it is better to have accessors for private types rather than public types in no more than three sentences.
