Real quick question about the "break" (sh.itjust.works)

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.

It's a very good lesson- to the point where I wouldn't be surprised if the teacher is deliberately putting an arbitrary restriction on the assignment.

It's not arbitrary. When you start out on a profession, the first thing a good instructor does is make you unlearn the things you already think you know before teaching you the things you need to know. Think of it this way: When you pick up a golf club and start hitting the ball, you'll drive it left and right. First thing you'll be taught is to only hit straight. Even if you think you should try to drive a curve ball, a good teacher will not allow you. Only when you have mastered the basics will he teach you to drive curved balls. So ignore your teachers advice at your own peril, but it will most likely set you up for an expert beginners career.

As a closer, I can tell you this much: I received the same advice almost 20 years ago and now, after being a professional developer for two decades, I can not recall more than five times when a break statement actually made more sense than to rethink the algorithm.
