Recently I decided to dig into code as well, ended up getting these books:
The C++ Language 4th Edition - By Bjarne Stroustrup (the creator of the C++ language)
Has both a quick rundown on using C++ in the first 6 chapters for those who have had some programming experience, as well as another 40+ chapters going though all of the details. Great book so far, really glad I bought it.
C++ Primer - 5th Edition - By Stanley B. Lippman & others
one is more of a reference book containing information on how to use C++ in certain situations. Have not had to use it too much so far, but looks good as well.
I wanted to have both an instructional book as well as a good reference, so far these two haven’t let me down. Especially the first one, it is easy to read & well laid out, and he goes through everything at a good pace. Highly recommend it!
For even more recommendations, check out thread on StackOverflow, The Definitive C++ Book Guide & List, it should point you in the right direction.
Good luck!
