Are you using Windows, Mac OS X, or Linux? And the second question I’d ask is, are you interested in learning basic programming?
If you’re using Linux, chances are, you already know some basic programming. If you’re using Mac OS X, which is Linux-based, you can easily code and compile your programs, too. If you’re using Windows though, you’ll have to jump through some hoops to accomplish the same thing, but it’s definitely doable.
I have a Windows desktop and a Macbook Pro. I code mostly on my Macbook Pro. And the biggest reason is the Terminal. Before I started studying Computer Science, command line stuff scared me, and I preferred doing everything through a graphical interface. Now that I’ve used a lot of command line stuff, for a lot of things I prefer running things command line instead of through a graphical user interface.
If you’re using Linux or OS X, you can easily code in C and C++, but if you’re running Windows, you might have to install some extra programs just to get that running.
I would prefer to do tutorials in C++, but most people probably would prefer PHP. It’s just C++ is easily transferable because so many other languages are based on C, so once you know the foundation, it’s easy to apply it. Another reason is C/C++ is more powerful than PHP and has strong data typing, which makes for better foundation than weak data typing in PHP.
So I guess what I’m getting at is if enough people have OS X, I’ll do tutorials in both PHP and C++, otherwise I’ll stick to PHP.
