| + | You may get any help you want, as long as you DOCUMENT it. Put the provenance of the help in your code as a comment at the top. For example: | ||
| + | <pre> | ||
| + | // Fred helped me with the toString() method. | ||
| + | // I found code for a nim sum online at xxxx and adapted it for my program. | ||
| + | </pre> | ||
| + | This will prevent problems of plagiarism. Please don't give each other code: write your own when you understand what is involved. Ask me if you are unsure or stuck: nobody needs to suffer for being stuck. | ||
| + | |||
| + | To get a grade, you must complete the bulleted items following it. Please make sure I give you a D before you go on to do more and get a higher grade. I should grade your program at least twice as you progress. | ||
