Beginner question

[wegifford <wegifford@GRUMPY.FORTLEWIS.EDU>]

Hey there,
   I am a beginner and I am covering pointers and have a few questions.  The 
book I am using is not giving me the best explanation.  The code makes tons of 
sense but I want to know a little more about what a pointer is.
   As I understand it a pointer variable is pointing to a variable location in 
memory.  So when passed in a function it is not exactly being passed but where 
the variable is located is being pass. What is a pointer exactly used for?  Is 
the previous explantion the answer.  If so when is the best time to declare 
and use pointers? What is a benefit of a pointer? Is it just speed?  Any help 
you all could give would shed light on this concept.

                                                        William
