Programming

I'm studying programming, and I don't agree woth my teacher. She basically said that if we use break (and continue too maybe) our test is an instant fail. She's reasoning is that it makes the code harder to read, and breaks the flow of it or something. (I didn't get her yapping tbh)

I can't understand why break would do anything of the sorts. I asked around and noone agreed with the teacher. So I came here. Is there a benefit to not using breaks or continues? And if you think she's wrong, please explain why, briefly even. We do enough down talking on almost all teachers she doesn't need more online.
