CSCI 261 - Programming Concepts - A8

This assignment is due by Thursday, April 30, 2020, 11:59 PM.
As with all assignments, this must be an individual effort and cannot be pair programmed. Any debugging assistance must be provided in accordance with the course collaboration policy.
Do not forget to complete the following labs with this set: L8A .

The Purpose

The purpose of this homework is to give you practice using objects of classes written by others. You can learn how to work with objects from others by looking at the member functions provided in the class.

The Goal

There are two parts to this assignment. First, you should refactor your class to only have private data members and a public interface using getters/setters as necessary. If your class uses helper functions, then make sure they are appropriately declared as private so a user cannot inadvertantly call one of them. Be sure to add const where appropriate for all functions and parameters do not modify the corresponding values.

Second, you must acquire three other magic items from your classmates to use (see the next section). Include their .h and .cpp files into your project. Then in your main.cpp create objects of these new classes. You can then present the user with a menu as to which magic item they want to use or use all four in sequence.

Code Sharing

Before sharing your "magic item" class with another, you should include your name in both files associated with your "magic item" class. In other words, your "magic item" class is your work; make sure you take credit for it!

In your main.cpp file, also include all names of people you shared your "magic item" class with.

If you are interested in having others use your awesome "magic item" class, feel free to post an advertisement on Piazza (with your email address so students can contact you for a copy of your code). However, you must follow these rules:

Do NOT post your "magic item" class source code on Piazza.
Do NOT share your main.cpp file. ONLY share your MagicItem.h and MagicItem.cpp files.
Post your advertisement as a NOTE (not a question). Any advertisements posted as a question will be deleted.

Functional Requirements

To receive full credit, the following requirements must be met:

Your "magic item" class should have at least two data members and, in addition to constructors and getter/setter functions, at least three other member functions. One of these other functions should be an introduction() function that tells the user how to use the "magic item" to win a prize.
Both files associated with your "magic item" class should include your name.
Your main.cpp must use at least three "magic items" written by others (in addition to your own), as well as let the user know whether he/she won the prize.

Grading Rubric

Your submission will be graded according to the following rubric.

Submission

Always, always, ALWAYS update the header comments at the top of your main.cpp file. And if you ever get stuck, remember that there is LOTS of help available. The following instructions are copied from How to Submit Homework.

It is critical that you follow these steps when submitting homework.

If you do not follow these instructions, your assignment will receive a major deduction. Why all the fuss? Because we have several hundred of these assignments to grade, and we use computer tools to automate as much of the process as possible. If you deviate from these instructions, our grading tools will not work. And that makes us very unhappy. And when we're unhappy, we give penalties. Thus, make us happy.

Submission Instructions

Here are step-by-step instructions for submitting your homework properly:

File and folder names are extremely important in this process. Please double-check carefully, to ensure things are named correctly.
1. The top-level folder of your project must be named Set8
2. Inside Set8, create 2 sub-folders that are required for this Set. The name of each sub-folder is defined in that Set (e.g. L8A, and A8).
3. Copy your files into the subdirectories ofSet8 (steps 1-2), zip this Set8 folder (steps 3-4), and then submit the zipped file (steps 5-11) to Canvas.
4. For example, when you zip/submit Set8, there will be 2 sub-folders called L8A, and A8 inside the Set8 folder, and each of these sub-folders will have the associated files.
Using Windows Explorer (not to be confused with Internet Explorer), find the files named main.cpp, YourClass.h, YourClass.cpp, OtherClass1.h, OtherClass1.cpp, OtherClass2.h, OtherClass2.cpp, OtherClass3.h, OtherClass3.cpp.

STOP: Are you really sure you are viewing the correct assignment's folder?
Now, for A8, right click on the main.cpp, YourClass.h, YourClass.cpp, OtherClass1.h, OtherClass1.cpp, OtherClass2.h, OtherClass2.cpp, OtherClass3.h, OtherClass3.cpp to copy the files. Then, return to the Set8/A8folder and right click to paste the files. In other words, put a copy of your homework's main.cpp, YourClass.h, YourClass.cpp, OtherClass1.h, OtherClass1.cpp, OtherClass2.h, OtherClass2.cpp, OtherClass3.h, OtherClass3.cpp source code into the Set8/A8 folder.

Follow the same steps for L8A, to put a copy of your lab's main.cpp into the Set8/L8A folder.

STOP: Are you sure your Set8 folder now has all your code to submit?
Now, right-click on the "Set8" folder.
1. In the pop-up menu that opens, move the mouse "Send to..." and expand the sub-menu.
2. In the sub-menu that opens, select "Compressed (zipped) folder".
STOP: Are you really sure you are zipping a Set8 folder with sub-folders that each contain a main.cpp file in it?
After the previous step, you should now see a "Set8.zip" file.
Now visit the Canvas page for this course and click the "Assignments" button in the sidebar.
Find Set8, click on it, find the "Submit Assignment" area, and then click the "Choose File" button.
Find the "Set8.zip" file created earlier and click the "Open" button.

STOP: Are you really sure you are selecting the right homework assignment? Are you double-sure?
WAIT! There's one more super-important step. Click on the blue "Submit Assignment" button to submit your homework.
No, really, make sure you click the "Submit Assignment" button to actually submit your homework. Clicking the "Choose File" button in the previous step kind of makes it feel like you're done, but you must click the Submit button as well! And you must allow the file time to upload before you turn off your computer!
Canvas should say "Submitted!". Click "Submission Details" and you can download the zip file you just submitted. In other words, verify you submitted what you think you submitted!

In summary, you must zip the "Set8" folder and only the "Set8" folder, this zip folder must have several sub-folders, you must name all these folders correctly, you must submit the correct zip file for this homework, and you must click the "Submit Assignment" button. Not doing these steps is like bringing your homework to class but forgetting to hand it in. No concessions will be made for incorrectly submitted work. If you incorrectly submit your homework, we will not be able to give you full credit. And that makes us unhappy.
