In C++, Create a class called Date that includes three data members: amonth(type int), a day(type int), and a year(type int). The Date class willhave a constructor with three parameters to initialize the three data members.You may assume the values provided for the year and day are correct, but makesure that the month value is in the range 1-12; if it isn't, set the month to1. Provide set and get functions for each data member. Provide a memberfunction displayDate that displays the date in format MM/DD/YYYY.Write a test program that prompts the user to input the month, the day,and the year and uses your Date class to output the formatted date.
Vrite a general program that creates a class called Worker that has 3 pieces of information as data members. These data members are a name, a surname, and a monthly salary. Include a constructor to initialize the 3 data members. You are expected to have get and set functions for every data member. Negative valued monthly salary should be set to zero. To test the software, write a test program that shows all the capabilities of employee class. Create 2 Worker objects and show each object's yearly earning. Then give every Worker a %10 raise and show each Workers yearly earning again.
User-defined Class: You will design and implement your own data class. The class will store data that has been read as user input from the keyboard (see Getting Input below), and provide necessary operations. As the data stored relates to monetary change, the class should be named MoneyChange. The class requires at least 2 instance variables for the name of a person and the coin change amount to be given to that person. You may also wish to use 6 instance variables to represent amounts for each of the 6 coin denominations (see Client Class below). There should be no need for more than these instance variables. However, if you wish to use more instance variables, you must provide a legitimate justification for their usage in the internal and external documentation.Your class will need to have at least a default constructor, and a constructor with two parameters:one parameter being a name and the other a coin amount. Your class should also provide appropriate get and set methods for…
There are two types of data members in a class: static and non-static. Provide an example of when it might be useful to have a static data member in the actual world.
I need a step by step explanation on how to create this project. Project: Flight Time Problem Description: Design two classes: Flight and Itinerary. The Flight class stores the information about a flight with the following members: A data field named flightNo of the String type with getter function. A data field named departureTime of the GregorianCalendar type with getter and setter functions. A data field named arrivalTime of the GregorianCalendar type with getter and setter functions. A constructor that creates a Flight with the specified number, departureTime, and arrivalTime. A function named getFlightTime() that returns the flight time in minutes. The Itinerary class stores the information about the itinerary with the following members: A data field named flights of the List<Flight> type. The list contains the flights for the itinerary in increasing order of departureTime. A constructor that creates an Itinerary with the specified fights. A function named…
Create a class Distance with feet and inches as a private dada members. Feet has int type and inches has float type. Create getdist & showdist functions which take values from user and then display these values respectively. Create another class Sign with sign as a private data member. Sign has a char data type. Class sign is inherited with distance class. Create getdist and showdist function to get values from user and then display all values. Create default & arrguments constructor also. Add a static data member named objCount, initialize it to 0 using scope resolution operator outside the class, add a function in the class to print the value of objCount.
Construct a Time class containing integer data members seconds, minutes, and hours. Have the class contain two constructors: The first should be a default constructor having the prototype Time(int, int, int), which uses default values of 0 for each data member. The second constructor should accept a long integer representing a total number of seconds and disassemble the long integer into hours, minutes, and seconds. The final member method should display the class data members.
Use Python Programming Language (The Stock class) Design a class named Stock to represent a company’s stock that contains: A private string data field named symbol for the stock’s symbol. A private string data field named name for the stock’s name. A private float data field named previousClosingPrice that stores the stock price for the previous day. A private float data field named currentPrice that stores the stock price for the current time. A constructor that creates a stock with the specified symbol, name, previous price, and current price. A get method for returning the stock name. A get method for returning the stock symbol. Get and set methods for getting/setting the stock’s previous price. Get and set methods for getting/setting the stock’s current price. A method named getChangePercent() that returns the percentage changed from previousClosingPrice to currentPrice.

Design a class called Date that has integer data members to store month , day, and year. The class should have two constructors; a default constructor that accepts no parameters, and a three-parameter constructor that allows the date to be set by the programmer. If the user creates a Date object without passing any arguments, or if any of the values passed are invalid, the default values of 1, 1, 2001 (i.e., January 1, 2001) should be used. The class should have three (3) member functions to print the date in the following formats: 3/15/16 March 15, 2016 15 March 2016 Demonstrate the class by writing a program that uses it. Be sure your program only accepts reasonable values for month and day. The month should be between 1 and 12. The day should be between 1 and the number of days in the selected month. I expect to see all uses of the constructors that you made, including the error checking. I also expect to see all uses of the 3 output functions in your program. You are responsible…
2. Car Class Write a class named car that has the following fields: ▪ yearModel. The year Model field is an int that holds the car's year model. ▪ make. The make field is a String object that holds the make of the car, such as "Ford", "Chevrolet", "Honda", etc. ▪ speed. The speed field is an int that holds the car's current speed. In addition, the class should have the following methods. ■ Constructor. The constructor should accept the car's year model and make as arguments. These values should be assigned to the object's year Model and make fields. The constructor should also assign 0 to the speed field.
