What libraries should I focus on?

[brokenbot]

To be an essential programmer, what libraries should I really focus on & get used to.

When I ask this question, I'm basing it off the general, ambiguous libraries.

Also, I know the basics -- input/output, classes, inheritance, functions, loops, and input/output.

What else would I need to know to become a better programmer?

You should learn the standard library: http://www.cplusplus.com/reference/

Your LOCAL library!

Go there and read books on advanced programming. 8^p

Well... it depends on what type of programming you plan to pursue. If it's GUI development start learning a GUI API, if it's graphics, take a look at the various graphics apis (opengl, SDL, etc... But at the most you should learn the standard library as Bazzy pointed out. As far as language independent concepts, you should grab a good book on Data Structures and Algorithms.

Each library tends to have its own individual purpose. If they serve the same purpose then they usually go about the purpose in different methods. It's up to you (I would probably research before you use something) on what you choose to use.
