does a victim have to state their side of the story in front of their attacker in court?

That IS generally how it DOES work!

You have to be brave and tell your side. Our jurisprudence system gives you the right to accuse in open court.

In the U.S. one of the rights people have is to confront their accusers. The idea is that if you are going to prison because someone said you did something, you should be able to hear what they are saying, ask questions, and respond. So if you are in the U.S. and it goes to trial and he wants to be, he can be there.

Sometimes, but not often, they allow victims to testify via closed circuit TV from another room. Usually this is with kids.

However, often, a defendant will wait until the last minute, hoping a witness will refuse to testify, and then if it's clear a case is going to court, plea bargain. Then the trial doesn't happen. So just because it looks like there will be a trial doesn't mean it's true. You may find you don't have to testify at all.

If you are in a different country, I don't know the rules. I'm sorry.

The accused has the right to face his/her accuser.

If there are other witnesses or sufficiently strong circumstantial evidence, of course not.

Sometimes the victim is justifiably worried that testifying against their attacker will make him come back and do something even worse, in retaliation for dragging them into court in the first place.

The legal idea is that both adversaries have the same standing in court, until judgment is given against one of them. In the case of children testifying, though, they are usually permitted to give their testimony in private, recorded for later use in court.

yes

Some states allow minors and abuse suspects to testify on video or in a different room than the defendant.
