Your question is a bit open ended so hard to answer, especially as there are so many different ways to answer it. The best (although generic) answer is to find a way to learn it while keeping yourself motivated. That in itself can be a big challenge.
With that in mind, I'd reccomend taking a look at the C++ workshop that was run here. While the actual workshop itself was conducted some time ago, all of the material is still here on Gamedev and still relevant.
You can find the forum section for it here, and there introduction is here
It does require a text be purchased, but on Amazon you can get it for less then $10 used, or for $20 on Kindle.
I didn't take the C++ workshop, but I did do a large percentage of the C# workshop, which looked to mirror it with regard to the projects, etc.
Is this the best first step? Maybe not. But I don't think it's a bad one.
Thank you I will defiantly look into that, and to clarify the question a bit more, I am basically looking for a good guide to help learn C++. Once again thanks this is what I wanted.
