A reference is a pointer without a pointer syntax. Like a pointer, a reference provides indirect access to an object. -- C ++ primer p29 Although a reference can also be used as a pointer, it is wrong to initialize a reference with an object address

Understanding the differences between reference and pointer can help you decide when to use reference and when to use pointer. In C ++, reference has the same capabilities as pointer in many aspects. Although most C ++ programmers have some
