Question

directions: use c++

Create a  ContactInfo class that contains the following member variables:

• name
• age
• phoneNumber

The ContactInfo class should have a default constructor that sets name = "", phoneNumber = "", and age = 0.

The ContactInfo class should have a constructor that accepts the name and phone number as parameters and sets name = <value of parameter name>, aAge = 0, and phoneNumber = <value of parameter phone number>.

The ContactInfo class should have accessor and mutator functions for each member variable.

The ContactInfo class should have a function called canVote that returns a boolean. It will return true if age is >= 18. Otherwise, it will return false.

Create three instances of this class in the main function

Write a C++ function (outside of the class) that will display (as shown below in the sample run) an instance of the ContactInfo class. Call the function to display the three instances you created in the main function.

Make sure your program conforms to the following requirements:
1. This program should be called ContactInfoApp.cpp. The header file should be called ContactInfo.h and place member function definitions in ContactInfo.cpp. You must submit these three files.

Include the basic header in your program. (5 points deduction if missing)

2. Properly set up the ContactInfo class and declare three instances of ContactInfo (45 points)

3. Write a C++ program that will create and display (as shown below in the sample run) three instances of the ContactInfo class. (25 points).

4. Add comments wherever necessary. (5 points)

Sample Run:

NOTE: not all possible runs are shown below.

Name: Kristen Lee
Phone Number: 555-2021
Age: 45
Can vote?: Yes

Name: Joe Smith
Phone Number: 111-9999
Age: 5
Can vote?: No

Name: Tom Hanks
Phone Number: 111-8888
Age: 75
Can vote?: Yes

General Requirements:

1) Include the header comment with your name and other information on the top of your files.

2. Please make sure that you're conforming to specifications (program name, print statements, expected inputs, and outputs, etc.). Not doing so will result in a loss of points. This is especially important for prompts. They should match mine EXACTLY.

3. If we have listed a specification and allocated a point for it, you will lose points if that particular item is missing from your code, even if it is trivial.

4. No global variables (variables outside of main) unless they are constants.

5. All input and output must be done with streams, using the library iostream

6. You may only use the iostream, iomanip, and string libraries. Including unnecessary libraries will result in a loss of points.

7. NO C style printing is permitted. (Aka, don't use printf). Use cout if you need to print to the screen.

8. When you write source code, it should be readable and well-documented (comments).

9. Make sure you test using G++ (to be sure it reports no compile errors or warnings!) before you submit the program.

10. Testing your program thoroughly is a part of writing good code. We give you sample runs to make sure you match our output requirements and to get a general idea of how we would test your code. Matching your outputs for JUST the sample runs is not a guarantee of a 100. We have several extensive test cases.

11. Program submissions should be done through the Canvas class page, under the assignments tab (if it's not there yet I'll create it soon.) Do not send program submissions through e-mail { e-mail attachments will not be accepted as valid submissions.

12. The four files you will submit via Canvas are ContactInfoApp.cpp, ContactInfo.h, ContactInfo.cpp, and your makefile.

13. Please make sure you've compiled and run your program before you turn it in. Compilation errors can be quite costly. We take 4 points per compiler error for the first 9 errors. The 10th compiler error will result in a grade of 0.

14. Only a file turned in through Canvas counts as a submission. A file on your computer, even if it hasn't been edited after the deadline, does not count. Now that you are familiar with the process of turning in a file through Canvas, we will not accept any excuses.

15. The student is responsible for making sure they have turned in the right file(s). We will not accept any excuses about inadvertently modifying or deleting files, or turning in the wrong files.

16. General Advice - always keep an untouched copy of your finished homework files in your email. These files will have a time-stamp which will show when they were last worked on and will serve as a backup in case you ever have legitimate problems with submitting files through Canvas. Do this for ALL programs.
