This lab is due by Tuesday, May 04, 2021, 11:59 PM.
As with all labs you may, and are encouraged, to pair program a solution to this lab. If you choose to pair program a solution, be sure that you individually understand how to generate the correct solution.
Concepts
Focus on defining a Date and an Event class from scratch.
Suggestion: Use NotePad or WordPad
Consider using NotePad or WordPad on your computer to write your code for this lab. Once you feel good about what you've written, then copy the code into your project. Doing this will help you see where you might make mistakes on the exam!
You should write a
main.cpp
that tests each feature of your class works as expected. You
will need to submit your class declaration files, your class
definition files, and your
main.cpp
file for this lab.
Date Class
We know you, as a Mines student, have a busy social life. Wouldn't it
be great to have a program that helped you keep track of all your
important dates (as in month, day, and year)? Write a Date class to
represent this "thing" to the computer. What properties do you need to
represent a date? Make these properties private to your class. (Again,
you should know why private makes sense; ask it you don't!) In
all functions that modify data members, you should always ensure the
values being set make sense. (You do not need to worry about leap
years.) Also, use a private helper function wherever one makes sense.
Functions you should include in your class:
- A default constructor that sets the date to 12/30/1950 (an extremely important date in our history).
- A parameterized constructor that allows a user to enter a new date, such as "8/1/1876" (another extremely important date in our history).
- Appropriate getter and setter functions. (Perhaps one setter function makes the most sense?)
- A private validate function that checks if the object is currently in a good state (e.g., months are 1-12, days are 1-31, year can't be negative, etc. Don't worry about having the correct number of days in a month or leap years.) and, if not, resets the date object to the default values. This function should be called by all functions that modify the date object.
- A boolean member function that returns whether the callee is earlier than the target date argument passed.
Extra credit points possible if (1) your default constructor outputs a "shout out" that illustrates you understand the significance of 12/30/1950 and (2) your parameterized constructor outputs a "shout out" that illustrates you understand the significance of 8/1/1876.
Event Class
Now that we have a way to represent a calendar date, we need a way to make
entries into a calendar. Create a new class called Event that
contains a data member of type Date created above.
In addition, add data members to track the event title and location.
Functions you should include in your class:
- A default constructor that sets the date to a default date (with the corresponding title and location for extra credit).
- A parameterized constructor that allows a user to enter a new
date object, title, and location (such as "8/1/1876" and its corresponding info for extra credit).
The parameterized constructor should operate on a
Dateobject and no longer the individual month, day, year pieces. - Appropriate getter and setter functions. The date setter should operate on a
Dateobject and no longer the individual month, day, year pieces. - A print function that prints the details in the form:
MM/DD/YYYY: Title (location).
Lab Submission
You will submit your solution to this lab with the rest of Set8. Detailed instructions for doing this are posted in Assignment 8.
