It honestly depends what you want to do with a programming language.
If it's games then it's obviously c++ using the DirectX API. However, you can use almost any language to create a game.
If you wanna get into web development then start off with HTML then CSS and then Javascript with Jquery.
If you just want to just get into it and see where is takes you then I recommend a C language. C++, C# and Java are all powerful and commericial languages and translate well to each other. JavaScript can just be confusing to newcomers.
Do some research,you'll figure it out
