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:
A class may have several constructors and it is called __________.
Step by step
Solved in 2 steps
- Question Create a class called Quadratic for performing arithmetic on and solving quadratic equations. A quadratic equation is an equation of the form ax2 + bx + c = 0 Where a !=0. Use double variables to represent the values of a, b, and c and provide a constructor that enables objects of this class to be initialized when they are created. Give default values of a = 1, b = 0, and c = 0. Create a char variable called variable to represent the variable used in the equation and give it a default value of x. The constructor should not allow the value of a to be 0. If 0 is given, assign 1 to a). Provide public member functions that perform the following tasks. add—adds two Quadratic equations by adding the corresponding values of a, b, and c. The function takes another object of type Quadratic as its parameter and adds it to the calling object. subtract—subtracts two Quadratic equations by subtracting corresponding values of a, b, and…Create a class called Account that a bank might use to represent customers' bank accounts. Your class should include one data member as int accountNumber and other of type float to represent the account balance. Your class should provide a default and parameterized constructor that receives an initial balance and accountNumber and uses it to initialize the data members. The constructor should validate the initial balance to ensure that it is greater than or equal to 0. If not, the balance should be set to 0 and the constructor should display an error message, indicating that the initial balance was invalid. The class should provide getter/setters for data members. The class should provide three member functions. Member function credit (float amount, int accountNumber) should add an amount to the current balance. Member function debit (float amount, int accountNumber) should withdraw money from the Account and should ensure that the debit amount does not exceed the Account's…Create a class called Account that a bank might use to represent customers' bank accounts.

The ProductionWorker class should have properties to hold the following data: Shift number (an integer, such as 1, 2, or 3) Hourly pay rate The workday is divided into two shifts: day and night. The Shift property will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Create an application that creates an object of the ProductionWorker class and lets the user enter data for each of the object’s properties. Retrieve the object’s properties and display their values.
- (Date Class) Create a class called Date that includes three pieces of information as datamembers—a month (type int), a day (type int) and a year (type int). Your class should have a constructor with three parameters that uses the parameters to initialize the three data members. For thepurpose of this exercise, assume that the values provided for the year and day are correct, but ensurethat the month value is in the range 1–12; if it isn’t, set the month to 1. Provide a set and a get function for each data member. Provide a member function displayDate that displays the month, dayand year separated by forward slashes (/). Write a test program that demonstrates class Date’s capabilities.Child Class: Vegetable Write a child class called Vegetable. A vegetable is described by a name, the number of grams of sugar (as a whole number), the number of grams of sodium (as a whole number), and whether or not the vegetable is a starch. Core Class Components For the Vegetable class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use instance data variables where appropriate a toString method that returns a text representation of a Vegetable object that includes all four characteristics of the vegetableJavaGiven the following class, called NumberHolder, write some code that creates an instance of the class, initializes its two member variables, and then displays the value of each member variable. public class NumberHolder { public int anInt; public float aFloat; }
- Create a class called ship that incorporates a ship’s serial number and location. Create another class angle which has two variables latitude and longitude. A member function of the ship class should get a position from the user and store it. Create object that should report the serial number and position. Write a main () program that creates three ships, asks the user to input the position of each, and then displays each ship’s serial number and position.Identify all the classes implement inheritance between them. (language cpp)You create a class by writing a(n) __________. a. blueprint b. class declaration c. initialization list d. object nameesign a class named WorkingDays. The purpose of the class is to store a value that represents number of hours worked and then convert it into number of days worked according to the formula given below: 8 working hours = 1 working day For example: v 8 hours would be equal to 1 day v 12 hours would be equal to 1.5 days v 18 hours would be equal to 2.25 days
