Question

Your instructor would like to thank to Marty Stepp and Hélène Martin at the University of Washington, Seattle, who originally wrote this assignment (for their CSE 142, in Java) This program focuses on classes and objects. Turn in two files named Birthday.cs and Date.cs. You will also need the support file Date.dll; it is contained in the starter project for this assignment. The assignment has two parts: a client program that uses Date objects, and a Date class of your own whose objects represent calendar dates. It is meant to be shorter than other recent assignments and is also worth fewer points. Part A (Birthday.cs, client program): The first part of this assignment asks you to write a client program that uses an existing MyDate class written by the instructor. The goal of Part A is to give you a bit of practice creating and using MyDate objects from a client's perspective and to give you an appreciation for the usefulness MyDate objects in general. Begin by prompting the user for today's date and for his/her birthday, first by month and then by day. Use this information to print the number of days in the month the user was born, and the number of days from today to the user's birthday. If the user's birthday is today, print a Happy Birthday message. Below are several example logs of execution from the program; user input is bold and underlined. Your program's output should match these examples exactly given the same input. What is today's month? What is today's month? 12 What is today's day? What is today's day? 15 What is your birthday month? What is your birthday day? What is your birthday month? 12 What is your birthday day? 15 There are 31 days in month #12 There are 30 days in month #9 Number of days until birthday 9/9: 309 What is today's month? Happy Birthday! What is today's month? 10 What is today's day? What is today's day? 19 What is your birthday month? What is your birthday month? 11 10 What is your birthday day? What is your birthday day? 30 There are 30 days in month #11 There are 31 days in month #10 Number of days until birthday 11/30: 103 Number of days until birthday 10/1: 364 Solve this problem using MyDate objects. The methods and behavior of each MyDate object are described on the next page. For Part A you can use an instructor-provided version of MyDate by downloading the starter project from the website. Inside that .ZIP you'll see a folder named SOLUTION_FROM_INSTRUCTOR that contains MyDate.dll. This Dynamic Link Library (DLL) file contains a sample implementation of the MyDate class (as described below). There are instructions in the Birthday.cs file that tell you how to use the instructor's version of the MyDate object or your own.
