Week 3: Lab Overview
TABLE OF CONTENTS
The purpose of this lab is to practice overloading operators. We will create and overload a Wings class.
You will create a Wings class and overload the operators for this class. Copy the C++ source code and screenshots into a single Microsoft Word document. Remember to hold down the Alt key when you make your screenshots so that only the active window is copied.

* Log in to your course in Canvas.
* Click on the Modules button on the left side.
* Click on Course Resources in the Introduction & Resources section (top).
* Scroll down to the Student Software Store section and click the Access Software Store button.
* Click on the Microsoft Imagine Premium tab, which is located just below the Product Search box.

Create a C++ project, and call it Week 3—overloading Wings.
• Create a Wings class using a separate header file and implementation file.
• Add the following attributes.
o Flavor (string data type)
o numPieces (short data type)
• Create a single constructor that uses default arguments.
o Flavor should be set to unknown if it is not given.
o numPieces should be set to 0 if it is not given.
• Create a destructor for the class.
• Create accessors and mutators for the attributes.

Overload the following operators in the Wings class.
Operator Description Example
+ addition wings3 = wings1 + wings2;
– subtraction wings3 = wings1 – wings2;
– negation wings2 = -wings1; // negative
++ pre-increment ++wings;
++ post-increment wings++;
= assignment wings2 = wings1;
>> input stream operator cin >> wings;
<< output stream operator cout << wings << endl; Help: Part 1 (Links to an external site.)Links to an external site. - Part 2 (Links to an external site.)Links to an external site. - Part 3 (Links to an external site.)Links to an external site. Step 3 Create a main method for your application that tests each of your overloaded operators. Run your program, and test it. Do the Wings objects add together logically? Do they increment appropriately? Can you display the Wings objects using simply output statements? Put a breakpoint at the top of your main method, and step through your code. Remember to use Step Out if you accidentally step into the C++ code library. Can you see how your application works?

At the top, put your information, including your name, course, Week 3 Lab, and the date. Run your application. Take screenshots while your application is running to demonstrate that it works properly. Remember to hold down the Alt key and the PrtScrn key at the same time (Alt + PrtScrn) to take screenshots of the active window only. Paste these screenshots into your Word document. Put the file name for each file in the Word document below the screenshots. Bold the file name, and increase the font. Copy and paste the code for each file below its file name. You should have three files for your project. Submit the Word document to the Week 3 Lab page underneath Assignments. PreviousNext
