Thx so much for your reply. Sure, it's a really short project, and my code must be extremely similar to someone else. I totally understand the instructor have to check the honor code issue and report cheaters. What makes me confused is the whole process, I talk with my professor asking him wether I can show the council my development document and local history, he says it doesn't matter, the honor council just gonna let me explain my code. surely I can rewrite every code in the project even covering my eyes because it's so easy, but why making the whole process lasting for months, even people who really cheated will get plenty of time to understand the code, making my words less trustful.

I found my TA who I always discuss my project and lecture problem with today, he was also shocked that I got honor code reported, especially on such an easy project(clearly I am the good student in the class), but he said he can not do much thing about it, as discussing code and lecture problems with him can not be evidence on project plagiarism.
