Depending on where you end up in the IT field you wont even use C/C++. I am a programmer and use C++ for almost all my home projects, but at work I use Perl, PHP, Java, SQL and *SHUDDER* Jython. Focus on one of then languages, the language you understand best at the moment, then branch out to other languages... my C++ background helped me a lot in learning other languages, just as those other languages have made me understand some things in C++ better.
