My choices in programming languages were pretty limited when I started as most of the courses were in C++ with some exploratory courses relating to other languages. I'd definitely suggest checking out at least one Object Oriented language like C++ or Java and one scripting language for the web, like PHP or Perl. Of course, the more you languages you learn the better, but I've found that once you learn a language pretty well, it's not that difficult to pick up new ones, as a lot of the language constructs are the same.
