Identical Linked lists

Two linked lists are said to be identical if they have the same date in the same order.
Eg: list A = 2->7->44 and  list B = 2->7->44 are said to be identical.

A simple iterative solution for finding out if the lists are identical.

int isIdentical(list a, list b)

{

     for(; a && b && a->data == b->data; a = a->next, b = b->next);

     return !(a || b);

}
