Create a User class with the following features (C++): A Private class member fname that is a string A Private class member lname that is a string A setter function setFName(string s) that sets the fname member A setter function setLName(string s) that sets the lname member A getter function getName() that returns the full name with a space between the first and last names Use the following code and save the class in a header file User.hpp
Can you help me with this code for C++ please: Modify the class Song you created for part 2 bydoing the following:(a) Add a default constructor that initializes the song to have invalid astitle and artist, and −1 as recording year.(b) Add a constructor Song(title) that initializes the song to thegiven title (that is, to the title given as argument). The artist andrecording year are initialized to unknown and −1, respectively. Theargument is a string.(c) Add a constructor Song(title, artist, year) that initializesthe song to the given title, artist and recording year. The first twoarguments are strings, the third one is an integer.(d) Replace the function equals(s1, s2) by a methodequals(other) that returns true if the receiver and theargument have the same title, artist and recording year.(e) Add a method less_than(other) that returns true if the title ofthe first song is less than the title of the second song. In case the titlesof the two songs are identical, the method returns true…
C++ Write a function named “createPurchaseOrder” that accepts the quantity(integer), the cost per item (double), and the description (string). It will return anewly created PurchaseOrder object holding that information if they are valid:quantity and cost per item cannot be negative and the description cannot be empty or blank(s). When it is invalid, it will return NULL to indicate that it cannot create such PurchaseOrder object. PurchaseOrder createPurchaseOrder(int quantity, double costPerItem, string description) { if(quantity < 0 || costPerItem < 0.0 || description == "") return NULL; else { PurchaseOrder p = new PurchaseOrder(quantity,costPerItem,description); return p; } } what's the issue with this function and how to rewrite it
C++ coding project just need some help getting the code thank you!
C++ Create a Temperature class that internally stores a temperature in degrees Kelvin. However, create functions named setTempKelvin, setTempFahrenheit, and setTempCelsius that takes an input temperature in the specified temperature scale, converts the temperature to Kelvin, and stores that temperature in the class member variable. Also create functions that return the stored temperature in degrees Kelvin, Fahrenheit, or Celsius. Write a main function to test your class. Use the equations below to convert between the three temperature scales. Kelvin = Celsius + 273.15Celsius = (5/9) X (Fahrenheit - 32)
Need help with a C++ commenting question: Indicate where the different constructors, assignment operator= and desctructor will run with a comment under the relevant line of code. Start in main and use the following tags to indicate the function that will run: Default constructor <object name>String constructor <object name>Copy constructor <object name>Assignment operatorDestructor <object name>Substitute the variable name for the object constructed or destructed. Use a comma to separate if multiple functions are run on a line. Code to comment on: #include <iostream> 2 using namespace std; 3 4 class Student { 5 public: 6 friend Student OutputDuplicate (Student obj); // friend function 7 8 Student (); // Default constructor 9 10 Student (string n); // String constructor 11 12 Student (const Student & obj); // Copy constructor 13 14 Student& operator= (const Student &…
Write a C++ program to create a class named 'student' with attributes as; the name of the student and marks obtained by the student. The class should include 2 member functions as; a function to input the student's name and marks scored. a function to display the student's name and marks scored. Your program should then display the student's name who has scored maximum marks in the main code. Note: It is mandatory to create a class, with its member functions.
I need help writing a C++ code. I need the code to be a class called date that has an integer data members to store month, day, and year. The class should have a three-parameter default constructor that allows the date to be set at the time a new Date Object is created. If the user creates a Date object without passing any arguments, or the values passed are invalid, the default values of 1,1,2001 (i.e, January 1, 2001) should be used. The class should have member functions to print the date in the following formats: 3/15/2020 March 15, 2020 15 March 2020 I also need the program to only accept real values for month and day. By this I mean month 1-12 and date 1- how ever long the month is.
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. Add a function signalStrength that returns the…
