Development A circular list in C

Hi All,

does anyone know what is meant by creating a circular list in C? I understand this would create a loop but that is the intention at the moment. It is for some work at Uni but I am in a bit of a bind and need a pointer at least.

Thanks

 

a circular list is a linked list where the last element has a pointer to the first element.

Code:

struct listitem {
  some data
  pointer to next element
}

list l = pointer to element a

listitem a = some data, pointer to b
listitem b = some data, pointer to c
listitem c = some data, pointer to a

(my knowledge of C is pretty crappy, but i think this gets the point across)

 

Yes, yes you do.... (tee hee sorry!)

Is it the actual code you are struggling on or the concept of a circular list?

 

I wondered if anyone would get that.

I understand the concept, I was having some problems putting it into practice. I think I have now figured it out. Not well however, though hand in for it was Friday, so I don' have to worry about it much.

Thanks for your help guys.
