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(n) __________ is a property that appears in a base class but expects to be overridden
in a derived class.
a. virtual property
b. concrete property
c. base property
d. abstract property

- Breed Class Create a Breed class with the following: Member Variables Create the following private member variables, all of type std::string: species_ breed_name_ color_ Constructors Create a default constructor for Breed that sets its species_ to "Dog", breed_name_ to "Pug", and color_ to "Fawn". Create a non-default constructor that receives a std::string for species_, breed_name_, and color_; in that order. The values from the constructor should appropriately assign the member variables. Accessors and Mutators Create accessors and mutators for all member variables, following the naming conventions covered in class. e.g. for species_, name the accessor Species, and the mutator SetSpecies. Pet Class Create a Pet class with the following: Member Variables Create the following private member variables: std::string name_ Breed breed_ double weight_ Constructors Create a default constructor for Pet that sets its name to "Doug" and weight to 15.6. The Breed object will…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…ngineering Computer ScienceQ&A Libraryin c++ Create a class time24, each object is a value represented the time of day in the form hours, minutes and seconds. Provide a constructor that enables an object of this class to be initialized when it is instantiated. The constructor should contain default values in case no initializes are provided. Provide Public member functions for each of the following operations: set the time, print the time, increment the time by one second, compare two times for equality, increment the time by one hour, determine if one time is “less than” (comes before) another time, and final print the time in format 12 hours. Include any additional operations that you think would be useful for your class. Design, implement, and test your class. in c++ Create a class time24, each object is a value represented the time of day in the form hours, minutes and seconds. Provide a constructor that enables an object of this class to be initialized when it is…
- Employee and ProductionWorker ClassesCreate an Employee class that has properties for the following data:Employee nameEmployee numberNext, create a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have properties to hold the following data:Shift number (an integer, such as 1, 2, or 3)Hourly pay rateThe 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. this.ReportViewer1.Employee(); cannot reference?Create a class called Employee that includes three pieces of information as data members—a first name (type string), a last name (type string) and a monthly salary (type int). Your class should have a constructor that initializes the three data members. Provide a set and a get function for each data member. If the monthly salary is not positive, set it to 0. Write a test program that demonstrates class Employee’s capabilities. Create two Employee objects and display each object’s yearly salary. Then give each Employee a 10 percent raise and display each Employee’s yearly salary again."The program instantiates and uses instances of a derived class with default and parameterized constructors. Write A Base Class Declare a class named RealProperty that could be used to describe a piece of real property. It should contain these private fields: streetAddress (string) squareFootage (int) taxes (double) Each field should have a comment documenting what it is for. Add public member functions as follows: The default constructor. The default constructor initializes the fields so that the street address is an empty string and all numeric fields are 0 or 0.0. Implement the default constructor inline using the member initialization list syntax. The constructor that accepts these data: street address (string), square footage (int), and taxes (double). Implement this constructor inline using the member initialization list syntax and call the mutator function for square footage in the body of the constructor. Add mutator member functions to set the fields. One member function for…
- Must be in C++ and cannot come from any online sources. Please be sure to include every part of the the question Design a Overdue class that calculates the amount to pay for an overdue library book. Its only class member variable, daysLate, should be set by a one-parameter constructor to whatever number of days is passed to it when an Overdue object is created. If no argument is passed, a default daysLate value of 1 should be used. The class should have just one public function, computeLateFee. This functions needs to accept two arguments, the number of days late and the "per day" late fee. Typically a late rate of 25 cents is appropriate but the user should be asked for the cost per day. That value will be passed into the computeLateFee function.. The computeLateFee function should use this information to compute the fee to be paid by the library patron. It should then return the fee amount to the main program where it is displayed. Demonstrate the class by creating a program…The __ class is the general class and the __ is the specialized class. Question 2 options: derived, base subclass, superclass base, derived child, parent# Pets## Breed ClassCreate a `Breed` class with the following: ### Member VariablesCreate the following private member variables, all of type `std::string`: 1. `species_`2. `breed_name_`3. `color_` ### Constructors1.
