What are friend classes?

Hi.
I'm just wondering what friend classes/functions are.
It's because I stumbled across them while analyzing a source.

If a function declared a friend you may access private members of
the class inside the body of that function. Declaring a whole class
a friend grants access to private members inside the scope of that
class.
