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?

Why does anyone bother to learn sepples? I remember when I tried. I thought I was really learning something, it felt difficult and strangely rewarding. Then I learned a decent language and I realize I had been trolled hard.
