I use pointers and references heavily in my day to day work...in managed code (C#, Java) and unmanaged (C++, C). I learned about how to deal with pointers and what they are by the master himself...[Binky!!][1] Nothing else needs to be said ;)

The difference between a pointer and reference is this. A pointer is an address to some block of memory. It can be rewritten or in other words, reassigned to some other block of memory. A reference is simply a renaming of some object. It can only be assigned once! Once it is assigned to an object, it cannot be assigned to another. A reference is not an address, it is another name for the variable. Check out C++ FAQ for more on this.
