Which of the following best describes inheritance? A. Ability of a class to derive members of another class as a part of its own definition B. Allows for implementation of elegant software that is well designed and easily modified C. Focuses on variables and passing of variables to functions D. Means of bundling instance variables and methods in order to restrict access to certain class members
Which one is FALSE about inheritance? A Contraction violates Liskov's substitution principle. B It is possible to misuse method overriding. C During analysis, we can discover taxonomies through generalization or specialization. D Strict inheritance is the default option in Java. E Abstract classes and interfaces are used to achieve specification inheritance.
Which of the following are not true about inheritance? (Multiple choice can be selected) A It is the pillar of the OOP paradigm that states that a class' variables and methods can be duplicated by its child classes by inheriting them. B It is done to avoid duplication of codes. C It is used to conceal the implementation of codes. D It is used to protect the integrity of data. E None of the other choices are correct.
Write a C++ program to implement the following level of inheritance. 1.Write getter/setters, display function, parameterized, default and copy constructor. 2. Write a calculateSalary() function in the Typist class and override the definition in permanent and casual. 3. Write a ‘main’ function and create objects of all classes in main and call the public methods of all classes
Explain the difference between the private inheritance and public inheritance.
When you are debugging an inheritance relationship, you can step through code and watch how C# creates the child object. Describe in your own words the process and explain why these steps take place. Teach your classmates about inheritance as you step through and debug the inheritance relationships. For example, which constructor executes first, the parent constructor or the child constructor? Why?
write a class implementation using C++ from the given class diagram TAKE NOTE OF 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

Q/// In this part of the course work you are required to change the definition of the Item_in_Stock class to make it an abstract class and change the getItemCat(), getItemName() and getItemDescription() definitions to make them abstract methods. You are then required to design and implement three classes which are derived from Item_in_Stock class to fully demonstrate the concept of inheritance and polymorphism. Implementation of HP_Laptop class in part II should have given you an idea of inheritance and polymorphism. Three sub classes, one class against each category (Computers, Laptops and Accessories), should contain appropriate constructors, instance variables, setter and getters methods and overridden methods for getItemName(), getItemDescription() and get_Item_details() method. You should be creative and come up with your own ideas of sub-classes. The question: Write code in Java with all these classes implementation and a program called Polymorphism_works with member method…

Create a parent class "universe" and write further program in c++ on "multilevel inheritance"using base class on your own .Also illustrate the resolving of ambiguity in the same. Please read the question carefully and then only write a code because earlier the solution was not appropriate.
oop in c++ Q2 We need to add fly behaviour for ducks. But we know that all the types of ducks cannot fly e.g Rubber duck cannot fly. If we add the fly behaviour to the parent class, what will be the problem in using inheritance now? What solution do you suggest for solving this problem? (Hint: Find out what is multiple inheritance, when and how do we use it) Q3 Implement the suggested solution in Q2. Q4 State any two problems with implementation in Q3, in terms of function's implementation and code reusability.
