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:
Assume that a class called Number, with private member n that is an integer, has already been declared. Please write the definition for the overloaded operator ++, used for preincrement. Code your function as if defined in Number.cpp (i.e. outside of the class declaration). That means use the class name and the scope resolution operator in your header. C++

- C++ please! Create a class called Employee that includes three data members: a firstname (type string), a last name (type string), and monthly salary (type int).The class will have a constructor that initializes the three data members.Include the set and get member functions for each data member. If the monthlysalary is not positive, the set function will set it to 0. Also include amember function that returns the yearly salary (i.e. twelve times the monthlysalary).Write a test program that prompts the user to enter the first and lastname of an employee as well as their monthly salary. The program will thenoutput the yearly salary of the employee, give them a 10 percent raise, andoutput the yearly salary again.PLEASE HELP: In c++ please The class function needs to be in a header file (.h) The main needs to be on the main .cpp file. Please try to avoid using -> operators. Looking for a solution without them. Any help is very much appreciated. Much thanks! Create a class AccessPoint with the following attributes: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Also, add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overlap that checks if two access points overlap their coverage and returns true if they overlap.

- Q2 Write a C++ class that include two integer values (x, y) in the private section and constructor function in the public section to set the value of a and b. The class should also contain two overload operators the first one is (-) that make subtraction of the variables a, and b of two objects (ex: 01.a- 02.a, o1.b - 02.b) and store the result in the new object. The second one is (*) that make the multiplication of the variables a, and b of objects (01.a*o2.a, o1.b*o2.b) and then store the result in the new object(named Res). Finally print the resultsRewrite the calculator program using a class called calculator. Your program will keep asking the user if they want to perform more calculations or quit and will have a function displayMenu to display the different functions e.g .(1 - addition, 2- subtraction, 3- multiplication, 4- division) Your program must have appropriate constructors and member functions to initialize, access, and manipulate the data members as well as : A member function to perform the addition and return the result A member function to perform the subtraction and return the result A member function to perform the multiplication and return the result A member function to perform the division and return the resultSubject name is C++ Writea program that demonstrate the use of constructor with default arguments for the following problem. Define a class person with data member as name and age. Create three objects with no argument, one argument name and two argument name and age. You are not allowed to create more than one constructor.
- Part I Implementation In this part you are asked to Implement C++ classes with their header files. • Define a Shape class which has property such as color, numberOfDors etc. This class should have parameterized constructor. • Define a Vehicle class which has property such as model, price, yearOfPro- duction. This class also have parameterized constructor and related methods • Define a Car class it should extend both of Vehicle and Shape classes at the same time, also have properties such as Horsepower.maxSpeed, fuelType etc. This class also should have parameterized constructors and related methods All class should have separated C++ and header files. Total 6 files. Note all class properties should be private and other are public. Consider the OOP concept.

Provide a constructorthat enables an object of this class to be initialized when it isinstantiated. The constructor should contain default values in case noinitializes are provided.Provide Public member functions for each of the followingoperations: set the time, print the time, increment the time by onesecond, compare two times for equality, increment the time by onehour, determine if one time is “less than” (comes before) anothertime, and final print the time in format 12 hours.Include any additional operations that you think would be useful foryour class.Design, implement, and test your class.All data members must be declared as “private”•No global variable canbe declared and used•Methods within the classand the requested functionscannot have “cin” or “cout” but it should make use of parameters and return value instead.•“cin” and “cout” should be done in main() or any testing functions•Make sure that you clearly show how the C++ class, its methods and all the functions are being called at least twice and print out its return value and its results properly. Define a new “changePassword” function that accepts 3 parameters:o A vector of User object pointerso User ID of the account to be changedo New passwordIt will return true if it can find that User object with the same user ID andchange the password for that User and false otherwise.Show how this function is being called and returning proper information.You can assume that the user ID is unique in the given vector object.
