Friend classes are used when two or more classes are designed to work

together and

need access to each other's implementation in ways that the rest of the world

shouldn't be allowed to have. In other words, they help keep private things

private.

For instance, it may be desirable for class DatabaseCursor to have more

privilege to

the internals of class Database than main() has.
