Const Correctness

[NewDev]

Hello All,

I am having a problem to digest the const concept of C++ programming language,especially the const pointers and references.
I always lose a track on usage and concept,Can some one suggest me a good online portal or books where I can study the concept in detail.

Thanks in advance.
