1. When they say "return" it's to be taken literally. You're supposed to have a neverending menu loop that, when a command is given, calls the corresponding command, and once that command has terminated, the fact that it is finished makes it fall bacck to the neverending menu loop

2. One way or another, this will require higher skills, where you learn to deal with what's called "exceptions"

You need a while loop that displays the menu. The way a while loop works, it will constantly go back to it

Ideally, you would have methods for the command. But it does the same as if they were in the loop too

The loop contains what you want to repeat. You want to repeat reading a command and executing the command given, so yes, it's in the loop

I have no idea of what it truly is like

if(incorrect)/else sounds like a way to do it. Even if a bit weird

Why would you question the if/else? Your issues are elsewhere

What are you doing?

Don't you understand the concept of repeating doing something?

I suppose the end effect is that. But how are you going to make it so that's what happens?
What have I already told you?

Yes. More specifically?

nah, didn't say that

Nah, didn't say that

I guess copy/paste what I said

Yup

neverending menu loop

That makes no sense

I don't understand why you're talking about other stuff

neverending menu loop

talk about that

not about something else

Here you go

Now make it so it checks the command and executes it
