If you want you can try C#, I personally like it since its simple yet powerful. The only problem is portability meaning you have to find some way to port your C# and whatever else to specific platforms like mac or linux which you can use Mono. This is coming from someone who started with C++ as his first language and I am still learning both to this date because it takes a long time to learn and master it. The reason I said C# is because you get into OOP(object oriented programming) fast since C# is strict on that subject. Its also easier to manipulate the windows api since in C++ you have to remember all this weird lettering crap and it can get annoying. I think the new implementation of C++11 changes it though so idk. Go for whatever language, I would research on google and look at a couple games written in the different languages. If you want to be in a game development company working on AAA titles then you should check out C or C++ since they deal with the low level part of programming but can do high level stuff too. For some reason Java is great also in certain areas but you need to know what to do or else your performance sucks so much. Minecraft had this problem for years until they finally improved it but you still feel the slowness of java. It also has the ability to be on many platforms, the phone is its primary target.
I would recommend these:
-python :Why? because its used a lot today in the real world and its pretty simple in terms of syntax and what not.
-C# : because of the direct push into OOP and the ease of programming, things become simpler and you can do things faster then the other C languages like writing a GUI.
-C/C++ : its still the standard language for video games in the AAA realm mostly but its very powerful and efficient. If you need speed and great performance these two make it possible but not like the other languages can’t do it also.
like some have mentioned as well there is the web development side of programming things. These are mostly considered mark up languages but anyways:
don’t mess with php yet since you need to know how to secure the server so no one just pops in on you. All of these languages have videos on youtube so check them out. Buying a good book won’t hurt either.
