The Dialog in front of the * with Dialog& Is the return type, a pointer and a reference (don't with address-of)
Behind is the name of the class: : () member function name is the fixed writing
Two the same because the return value is an object of this class, the return value may also be other classes of objects, of course also can return an int, float the basic types of
Int Dialog: : test () {} is right
