5It's a reference. Speaking of which, allow me to refer you to our [excellent book list](https://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list). – StoryTeller - Unslander Monica Mar 25 '18 at 19:18

Thanks guys. I thought that references and pointers are the same thing. – Etwus Mar 25 '18 at 20:02

The & means a reference here, not the address operator. So func() returns a reference to an int. When you call it, it returns a reference to the variable a, and when you assign it to the int b, it copies the value in a to b.
