How Do I Fix This? I'm Not Sure What I Should Use For 'Strong Identifier'

You made a silly mistake. You have an extra ) or } somewhere. If you posted your code, I could probably find it for you.

This needs to be placed inside a function or erased. If you don't intend to erase it, you need to slightly change it. I've made the changes necessary in this post.

Because ... That's not a function. Not even close. (And don't forget to declare a prototype in the header when you make a new function!) You should really go learn C/C++ and try again at this in a couple of months.
