Returning an array in C++

PLEASE /prog/ help me out here. I've read and tested at least 5 "answers" to my question that I've found on google, but I can't get any of them to work. You guys are better than them though, right?

I wanted to call an array by reference in a function. Then, I learned that that was impossible. I tried returning the array, but you can't do that either.

Apparently, I need to do some shit with pointers to return the array. How the fuck do I do this?

...In C, you take an pointer parameter, and modify the array in place.
...and don't get any of the features you spent your whole post including. Write an equivalent C program, why don't you?
