Reference Variables and Functions Returning References

• References should be prepended with 'r'.
• Place the & close to the variable name not the reference type when working with reference variables. With function declarations, the & should be close to the reference type.
• Functions returning non const references should be prepended with 'r' to make it clear that a modifiable is being returned.

class Test
{
public:
    void                doSomething(StatusInfo &rStatus);
    StatusInfo&         rStatus();
    const StatusInfo&   status() const;

private:
    StatusInfo &mrStatus;
}
