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:
Step by step
Solved in 2 steps
- You are going to make an employee management system. In this lab, you have to createan Employee class only. Employee class fields are: Employee Name, Employee ID, and EmployeeGender. The member functions include the getters and setters for all the member variables anddisplay () function to display the data. In the main function, first create two Employee objectsand allow the user to enter data in these objects. Secondly, display the data from these objects.In Java programming What is the difference between a static data member and an instance data member? Declare a unique class (i.e., different from a classmate's posting) that contains an instance data member and a static data member (in the same class). Explain how each of the members is used in the class.Language:C++ Give the definition of a class named Product whose objects are records for ane-commerce system. A Product record has the product’s ID, Name, Description and Price. Besure your class has wrapper (get & set) methods for all member variables, 2 public membermethods named ‘calculateBill’ and ‘printProductDetail’ and at least 1 private memberfunction with meaningful implementation. Declare the object of Product class in mainfunctions and use all its member variables and methods.
- Class field corruption must be prevented.Create a class of subtraction having two private data members. Create classmethods to get data from users and for subtraction of data members.appropriate access modifiers for class methods.What is the accessibility of a protected attribute that is in a public class? A. Any class has access to this attribute. B. Only the class and its subclasses have access to this attribute. C. Only the class itself has access to this attribute. D. Any class in the same package has access to this attribute.
- Create a class of any domain i.e. university, showroom, student, shop. Also mention attributes for them and initialize the values using constructor and show the values for each object using custom function (out side the class) hint: min no of objects 2Create a class of subtraction having two private data members. Create class methods to get data from users and for subtraction of data members. Use appropriate access modifiers for class methods.Using the scenario of Object oriented programming Q1 Write a program that defines a class with a data member to holds a “serial number” for each object created from the class. That is, the first object created will be numbered 1, the second 2, and so on. To do this, you’ll need another data member that records a count of how many objects have been created so far. (This member should apply to the class as a whole; not to individual objects. What keyword specifies this?) Then, as each object is created, its constructor can examine this count member variable to determine the appropriate serial number for the new object. Add a member function that permits an object to report its own serial number. Then write a main() program that creates three objects and queries each about its serial number. They should respond I am object number 2, and so on.
- You need a method of protecting class fields against unintended corruption.In a few words, explain what memberwise assignment entails.Create a class of any domain i.e. university, showroom, student, shop. Also mention attributes for them and initialize the values using constructor and show thw values for each object using custom fucntion (out side the class) hint: min no of objects 2
