I.D I am a software engineer I work mostly with VB and SQL server , but I have also worked with Pascal, Delphi, Cobol. In the university I learned mostly C (which I never used but that's just coincidence). What is the most important to learn is the basics that apply for all programming languages. In the beginning you should read some books on : algorithms , data structure , object oriented languages,databases, interface design, and then decide on which language to focus. Or you can focus on web programming.
And I quote Marvel :
Something that is important to know is that programming is only 10% the language, the rest is problem solving. So if you start with one language, moving to another is not hard.
Which is 101% true. If you know the basics then you can move from one language to another. I learned most languages on work. 3 years ago I was working on programms about Bank systems and Stock Market, now I work in Marine Software. Totally different area , different languages.
Good luck with what you decide and we are here for any help you might need.
