linked list memory diagram

Question

struct letter
{
char ch;
struct letter *ptr_next;
}
*ptr_first,*ptr_this;
//ptr this contains the address of the first node and ptr this contains the address of last node added.

A word chair has to be inserted in the linked list such that C goes into the first node,h in the second and so on.. The attached picture is the memory diagram to fill. I also added what i tried.Please guide me if i am wrong. Thanks in advance..

Answer 1

the answer to your question: no. no, because you left one question mark unresolved at ff15.

Answer 2

The problem is the padding bytes your compiler will insert in your struct letter. The addresses of contiguous struct letter objects will never end up like in your drawing.
