Questions concerning linked lists are the most-often asked questions out there. Be very

most common questions that I've come across are the following:
Read the Stanford Survery of Linked List Problems. It has answers for all of the above problems as well as an in-depth look at implementing everything to do with linked lists.
I found this C++ FAQ by Bjarne Stroustrup, original creator and implementor of C++, very helpful. Interviewers will often ask you about the apparent oddities in the language and often the answers to those questions will be found here. The likelihood of you finding the exact question you'll be asked on this FAQ is pretty low, but it will get you thinking in the right way to consider the impact of these decisions and be able to reason coherently about new ones. It's an interesting read for anyone that has every wondered "Why?" about C++.
Also, for a quick review of the C++, this C++ Primer provides a short rundown of the most popular features of C++.
