REFERENCES 

References are usually used for function argument lists and function 
return values. So following are two important subjects related to C++ 
references which should be clear to a C++ programmer: 



Concept                  Description 

References as parameters  C++ supports passing references as function 
                                parameter more safely than parameters. 

Reference as return value  You can return reference from a 
                                C++ function like any other data type.
