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.

Have you ever wondered how you could delete vector elements in C++ in a loop? This is a way to do it... 

Don't confuse references for pointers. References are another name for an object which currently exist. They are not Pointers.
