So what are Iterators? Iterators are an efficient method provided by C++ to traverse the elements of any type of containers such as: Vectors, Deques, Lists, etc. An iterator represents a certain position in a container.

There is a new type of for-loop in C++ 11 that you may want to give it a try. In my opinion is more clean and efficient, but you should decide yourself.

I have heard of Lambda functions for a while but never had the courage to use them. Well, last week I was forced to use them. They are actually not that bad to learn. I want to give you a brief overview on how to use them.

One of the new features in C++ 11 is the automatic type deduction: auto. With auto you can declare a variable or an object without specifying its type.

Avoid wasteful overhead on user-defined types by using pre-increment rather than post-increment.
