Hello everyone. Home help = homework help :) can't change it now

I'm running into an error, expected initialize before "int menu()"

I have been playing around with it for a bit but I have not figured out how to get rid of the error.

When I think I got rid of the error, I ended up getting 40 new errors on the next compile. As of right now I am using quincy and with this code it is only showing the one error.

I'm aware there might actually be lots of more errors that are not showing up yet.

My assignment link is here:

Here is code:

```

int menu()
