On my honor:

- I have no discussed the C++ language code in my program with anyone other than my instructor or
the teaching assistants assigned to this course.

- I have not used C++ language code obtained from another student, or any other unauthorized source,

- If any C++ language code or documentation used in my program was obtained from another source,

comments of my program.

- I have not designed this program in such a way as to defeat or interfere with the normal operation
