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.
In C++ design a class named Triangle that extends GeometricObject. The class contains the following: Three double data fields named side1, side2, and side3 to denote three sides of the triangle. A no-arg constructor that creates a default triangle with each side 1.0. A constructor that creates a rectangle with the specified side1, side2, and side3. The constant accessor functions for all three data fields. A constant function named getArea() that returns the area of this triangle. A constant function named getPerimeter() that returns the perimeter of this triangle. Submit the following: Draw the UML diagram that involves the classes Triangle and GeometricObject. Implement the class. Write a test program that prompts the user to enter three sides of the triangle, enter a color, and enter 1 or 0 to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the color and filled properties using the input. The program should display the…
C++ (C plusplus) Requirements: Use the given class “User” (below) All data members must be declared as “private” No multiple return statements within a function or method No global variable is allowed to be declared and used (constants are ok) Methods within the class and the requested functions cannot have “cin” or “cout” but they should make use of parameters and return value instead unless it is explicitly stated. “cin” and “cout” should be used in main() and testing functions You are required to provide main() and testing functions if any that contains testing code to show how you have tested your classes, methods, and functions. You must show at least one call for each method and function and print out its return values and results correctly. Define a new exception class named “BadValueException” that must inherit from the exception class. It will manage and capture the general invalid integer and double value. It must be able to describe the reason for the error and save…

Creating a Class in C++ Summary In this lab, you create a programmer-defined class and then use it in a C++ program. The program should create two Rectangle objects and find their area and perimeter. Instructions Ensure the class file named Rectangle.cpp is open in your editor. In the Rectangle class, create two private attributes named length and width. Bothlength and width should be data type double. Write public set methods to set the values for length and width. Write public get methods to retrieve the values for length and width. Write a public calculateArea()method and a public calculatePerimeter() method to calculate and return the area of the rectangle and the perimeter of the rectangle. Open the file named MyRectangleClassProgram.cpp. In the MyRectangleClassProgram, create two Rectangle objects named rectangle1 and rectangle2 using the default constructor as you saw in MyEmployeeClassProgram.cpp. Set the length of rectangle1 to 10.0 and the width to 5.0. Set the length…
This is for c++ help. Requirements: You are working for a meteorologist to maintain a list of temperatures and some related statistics for a month. Create a class called Temperature that stores temperature readings (integers) in a vector (do not use an array). The class should have data members that store the month name and year of when the temperature readings were collected. Constructor(s): The class should have a 2-argument constructor that receives the month name and year as parameters and sets the appropriate data members to these values. Member Functions: The class should have functions as follows: Member functions to set and get the month and year variables. A member function that adds a single temperature to the vector. Both negative and positive temperatures are allowed. Call this function AddTemperature. A member function to sort the vector in ascending order. A member function to compute the average (x̄) of the temperatures in the vector. The formula for calculating an…
Important requirements for all questions: • All data members must be declared as “private” • No global variable is allowed to be declared and used • Methods within the class and the requested functions cannot 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.
C++ Assignment---This is an almost finished code, please complete it. Make changes if necessary. Objectives • To apply knowledge of classes and objects Instructions Implement all of the following, each in a separate Visual Studio project (and/or solution). 1. Define a class called CounterType to implement a simple counter. The class must have a private field (data member) counter of type int. You must also provide methods (member functions), including the following: a. A constructor to set the counter to the value specified by the user b. A constructor to set the counter to 0 c. A method to allow the user to set the counter to a value they specify d. A method to increment the counter by 1 e. A method to decrement the counter by 1 Your code must ensure the value of counter is never negative. If the user calls a method to attempt to make the counter negative, set the counter to 0 and print out an error to the user (e.g., “The counter must not be negative.”) Do not take any user input…
C++ PROGRAM STRING MANIPULATION Create a class Class1 with a string data member ‘paragraph’. Provide a constructor and getParagraph() method in the class. The constructor just assigns NULL to the data member. getParagraph() method must read a paragraph from user. The paragraph should contain at least 30 words. If there are less than 20 words, the program must ask user to enter paragraph again. Create another class Class2, and make it a friend of the class Class1. Provide a function getSubString(Class1 &obj1, int startIndex, int lastIndex) with return type string in the class Class2 which accepts an object of class Class1 (by reference) and two integers. The getSubString() function should return the substring starting from location startIndex and ending at location lastIndex. Class2 must also contain a store() function that stores the substring in a file. Print screenshot of substring stored in file as well.
Java code Lab 4 Problem Statement Create a class named AirConditioner in its own file. (The main method should be in a different file.) The class should contain the following: Three public constants named HIGH, MEDIUM, and LOW with values of 1, 2, and 3 to denote the air conditioner fan speed. A private int data field named speed that specifies the speed of the air conditioner fan. (The default is 1 for high.) A private boolean data field named on that specifies whether the air conditioner is on or not. (The default is false.) A private double data field named temperature that specifies the temperature setting of the air conditioner. (The default is 72.0.) A private String data field named model that specifies the model name of the air conditioner. (The default is "Iceberg".) The accessor and mutator methods (getters and setters) for all four data fields. A no-arg constructor that creates a default air conditioner, with all the default settings. (Do not create a full constructor or…
TIME CLASS (Language: C++) - Write a time class named timeClass - Write code to demonstrate that it works - The timeclass class will be named timeClass - The class must have these 3 constructors: #1) timeClass(); #2) timeClass(int h, int m, int s); #3) timeClass (string timeIn); - The string constructor must be capable of being separated by colons or blanks time in the 24-hour format: example 23:11:07 or 9:4:9 or 11 31 27 - DO NOT use some system functions for this assignment. You must write the code. - Yes, you can convert from string to integer stoi ( string). - In addition to the constructors, you should supply a set of getters (Accessors) getH, getM getS - In addition to that, add mutators that allow the individual setting of Hours, Minutes and Seconds: setH(int), setM ( int ) setS( int ) Include this setter ( Mutator) setTime( int NumSeconds); - So if I call setTime( 7673) you would know that that is: -- hours, -- minutes and -- seconds seconds = 53 7673…
