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;

Please Help me with this problem..!!

Write a procedure Split1(A, NA, B, NB, C, NC) that copies elements of an array A of NA real
numbers to arrays B and C so that the array B contains all elements of the array A with odd order numbers (1, 3, …)
and the array C contains all elements of the array A with even order numbers (2, 4, …). The arrays B, C and their
sizes NB, NC are output parameters. Apply this procedure to a given array A of size NA and output the size and the
elements for each of the resulting arrays B and C.
