OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
5- If a class does not have the extend keyword, then it
a) does not have a parent class.
b) inherits from the Object class.
c) inherits from the Default class.
d) inherits from the Parent class.

- Class members are accessed via the________ operator in conjunction with the name ofan object (or reference to an object) of the class or via the_____________ operator in conjunction with a pointer to an object of the classQuestion 8 When a class uses dynamic memory, what member functions should be provided by the class? Group of answer choices All of the above. The copy constructor. The assignment operator. A destructor.Write a class Medical Staff that contains an attribute ID to store staff’s identity. The class contains member functions to input and display ID. Write a child class Doctor that inherits Medical Class. It additionally contains an attribute to store doctor’s PMDC number. It also contains member functions to input and show the PMDC number. Write another class Skin Specialist that inherit Doctor Class. It additionally contains an attribute to store working experience as specialist. It also contains member functions to input and show the experience. Test these classes from main() by creating objects of derived classes and testing functions in a way that clear concept of multi-level Inheritance.b) Recall the Complex class that we implemented in operator overloading concept. Your task is to provide implementation of the following method. friend ostream& operator<< (ostream& , const Complex& )
- is the term used to describe the process through which a member of one class becomes a member of another.create class employee with properties id, name, salary, write accessor, mutator & constructor for the class. in main create three objects of class & find the employee with the highest salary.create class employee with properties id, name, salary, write accessor, mutator & constructor for the class. in main create three objects of class & find the employee with the highest salary.Create a class Person with data members Name, Age and Address. Create another class Teacher with data members Qualification and Department. Also create another class Student with data member Program and Semester. Both classes are inherited from the class Person. Every class has at least one constructor which uses base class constructor. Create member function Show Data () in each to display the information of the class. C++
- is the term used to describe the process of transforming a member of one class into a member of another.C++ PROGRAM Create a class MyClass with an integer data member ‘secret’. Provide a constructor and display method in the class. Create another class, MyFriendClass and make it a friend of the class MyClass. Provide a function change() in the class MyFriendClass which accepts an object of class MyClass (by reference) and an integer. The change() function should assign the integer passed as an argument to the data member ‘secret’ of the object received as input. Sample Run : MyClass m(2) ; MyFriendClass mf ; mf.change(m,10) ; m.display() ; //Should print 10A base class’s____________ members are accessible within that base class and anywhere thatthe program has a handle to an object of that class or one of its derived classes.
- Some of the characteristics of a book are the title, author(s), publisher, ISBN, price, and year of publication. Design a class bookType that defines the book as an ADT. Each object of the class bookType can hold the following information about a book: title, up to four authors, publisher, ISBN, price, and number of copies in stock. To keep track of the number of authors, add another member variable. Include the member functions to perform the various operations on objects of type bookType. For example, the usual operations that can be performed on the title are to show the title, set the title, and check whether a title is the same as the actual title of the book. Similarly, the typical operations that can be performed on the number of copies in stock are to show the number of copies in stock, set the number of copies in stock, update the number of copies in stock, and return the number of copies in stock. Add similar operations for the publisher, ISBN, book price, and authors. Add the appropriate constructors and a destructor (if one is needed). Write the definitions of the member functions of the class bookType. Write a program that uses the class bookType and tests various operations on the objects of the class bookType. Declare an array of 100 components of type bookType. Some of the operations that you should perform are to search for a book by its title, search by ISBN, and update the number of copies of a book.Use C++ Create a class called Fruit. Add one member variables name. Add only one getter function for the name. The get function returns name. Implement a constructor that expects name value and assigns it to the member variable. This class doesn't have an empty constructor. Create a subclass of Fruit named CitrusFruit. The CitrusFruit class has two member variables weight and color. Add a constructor which expects weight and name and color.Pass name to the base constructor and set weight and color to it's member variable. Write a program that has an array of 3 Fruits, and an array of 3 CitrusFruits. Feel free to give the name , weight and color to the object as your choice. Use loops to print out the array properties to the terminal screen.10.If all the classes used parameterized constructors and no default constructor then _________ i The object of lower level classes can’t be created ii Object of lower level classes must call parent class constructors explicitly iii Object of lower level classes must define all the default constructors iv Only object of first class can be created, which is first parent
