Circularly Linked List

Count elements of circularly linked list

Step 3: Count elements of the circularly linked list To count all elements of the circularly linked list, we will need a loop to traverse through the circularly linked list. We will let a pointer (i) of ListElem type to point to the pfirst then move the pointer to its next element and increase the number of item(t) one at a time by using a while loop until the end of the circularly linked list is reached.   //C code to count the number of items in the list
int countitem(ListElem *L)
  ListElem *i;
  int t;
    while(i!=L){ //not the end of the list

    return t;

   else return 0;
