A lot of people have been asking this question, and thats what this forum is flooded with. I was hoping to come into this forum and see a little bit of knowledge passed around; however, it hasn't been. So, since I have nothing better to do at the moment, I decided to compile a list of very helpful resources. Both from my own personal favorites as well as a few given from gameuser.

To start with, what do you want to use C/C++ for anyway?
If you want to start writing games, you're definately a far cry away from that. However, it wouldn't hurt to start now because it will take you time to learn anyway.

Game design/programming - To begin there have been a lot of suggestions by people, and the ones I consider reliable are real game programmers. From what GameDev.net, as well as a few programmers from Blizzard Entertainment have told me. They say your better off by just learning C++, mainly because that is the primary language for the graphical libs; DirectX, OpenGL, SDL, etc. However, it is true that C++ is a superset of C.

Also it has been recommended that before you get into DirectX and OpenGL kinda stuff, that you have a good undertanding of the Win32 API first, you don't need to know every little detail but it helps.


But lets get the party started by sharing a few very good C/C++ sites with extremely useful tutorials:

--- ALWAYS BEING UPDATED ---

Will be updated with more information, when information is found, or someone suggests a good link.

[Newbie/No Programming Experience]
[You must be registered and logged in to see this link.] -- Most commonly posted site for tutorials, decent in my opinion. It gives you a very quick and broad overview of the language.
[You must be registered and logged in to see this link.] -- Decent beginners tutorials. However, like most books they use a lot of computer terms.
[You must be registered and logged in to see this link.] -- Great site with lots of tutorials for all skill levels, when it's up that is...
[You must be registered and logged in to see this link.] - Same thing that GameTutorials.com was doing for free until they started charging you for the tutorials. The great part about this is you get them for FREE!
[You must be registered and logged in to see this link.] - Numerous tutorials that range from good to bad, and skilled to newbie.
[You must be registered and logged in to see this link.] - Links to a LOT of other tutorials that are not yet listed here.
[You must be registered and logged in to see this link.] - Site titled "Learn C++ in 21 Days"



[Intermediate]

[You must be registered and logged in to see this link.] -- Decently written OpenGL tutorials, lacks a bit of function definition but good overall, and highly linked to. He has bad coding habits, so don't copy and paste the stuff, just use it for learning.
[You must be registered and logged in to see this link.] -- Once you've learned to program, you should start developing a good programming style so other programmers dont have to decode what you're trying to say. I agree with 80% of this document, so just use it as a guideline.
[You must be registered and logged in to see this link.] - Very well written tutorials, they have a LARGE variety of them as well. Most of them are in the Demos section, they will be adding articles soon!
[You must be registered and logged in to see this link.] - Good reference for OpenGL Functions, similar setup to manpages.
[You must be registered and logged in to see this link.] - Great site, full of content, and explains OpenGL VERY well.
[You must be registered and logged in to see this link.] - More technical than the red version, and again LOTS of content.
[You must be registered and logged in to see this link.] - Contains a lot of links to informational pages on the selected subject.
[You must be registered and logged in to see this link.] - NEWLY ADDED - The DirectX version of NeHe's tutorials.
[You must be registered and logged in to see this link.] - An interesting way to teach OpenGL, havent tried it but I will soon. It's tutoring application that visually teaches you the library.
[You must be registered and logged in to see this link.] - Great DirectX tutorials, however he uses a wrapper to teach you how to use them. So it's definately not a good way to learn.
[You must be registered and logged in to see this link.] - NEWLY ADDED
[You must be registered and logged in to see this link.] - Decent place to get started on DirectX or OpenGL, coding by example, usually a bad way of learning, but thats why it's in the advanced section.
[You must be registered and logged in to see this link.] - DirectX 8 Tutorials, however they are decently written. DirectX 8 was the last version to using the old fasion BitBlt() function.
[You must be registered and logged in to see this link.] MSDN is ALWAYS a bookmark, and should be for ANY programmer.
[You must be registered and logged in to see this link.] - OpenGL.org has a lot of resources, very helpful for OpenGL ofcourse.
[You must be registered and logged in to see this link.] - OpenGL tutorial that uses Language C.
[You must be registered and logged in to see this link.] - A LOT OF TUTORIALS!
[You must be registered and logged in to see this link.] - NEWLY ADDED



[Advanced]

[You must be registered and logged in to see this link.] Good tutorials, and very technical.
[You must be registered and logged in to see this link.] - A lot of topics are discussed here, very informational.
[You must be registered and logged in to see this link.] - NEWLY ADDED - This one varies on skill levels, lots of advanced stuff here though.
[You must be registered and logged in to see this link.] -- Programming as a profession? Want to keep your job? This documentation will help you write unmaintainable code, so if they fire you. They will have one hell of a time trying to figure out your code.



[Video Tutorials]

* I don't really think video tutorials teach a beginning user much, but some people might be able to learn from them. So, I decided to add this section to the list. *
[You must be registered and logged in to see this link.] - Video tutorial that is split into 16 parts. The guy has a UK Accent, and is not entirely boring to listen to. Submitted by kratos15



[C/C++ IDE's] - NEWLY ADDED

[You must be registered and logged in to see this link.] - Popular free IDE for both *nix and Win32
msdn.microsoft.com/express - Another popular free IDE recommended, also if you plan on using this don't forget to download the Platform SDK
[You must be registered and logged in to see this link.] - The famous Java IDE can also be a C/C++ IDE with a somewhat simple plug-in installation



[Graphic Libraries] - NEWLY ADDED

Game Hacking University - A great large listing of game hacking tutorials. Including tutorials on creating trainers in C/C++ as well as a few other hacks.




[Graphic Libraries]

[You must be registered and logged in to see this link.] - Simple DirectMedia Layer (SDL) - Quick and easy to learn 2D Library, that also works very well with OpenGL
[You must be registered and logged in to see this link.] - A lot like SDL, but not as "clean" as SDL




[align=center]*** There is a variety of Game/Graphic Developement Engines and Libraries, I will just list a few that I have found ***
[/align]


[Game/Graphic Engines]

[You must be registered and logged in to see this link.] - Object-oriented Graphics Rendering Engine - 3D
[You must be registered and logged in to see this link.] - Irrlicht Engine Open Source - 3D
[You must be registered and logged in to see this link.] - Some what a library and somewhat an engine - 2D




A lot more to Come !
