reference VS pointer variables

what is the the difference between reference variables (from C++) and pointer variables (from C)?

C++ has pointers too... Pointers can point basically anywhere. Reference variables always point to a specific object. Once you get into using structures and stuff you'll understand this more.

As a tipp: try to use reference wherever possible as they tend to produce less memory errors and still provide polymorphism as pointers.

References (&) can't be assigned to other variables/objects and must be initialised; pointers are happy to be null and reassigned.
