Computer Science question
Being a student in Computer Science, is it a general necessity to know C/C++ instead of all the other fancy top-market advertising languages such as Java/VB/C#? I'm no stranger to each language, btw. I feel I need to "focus" on one, though. Each language has their own obstacles.. I don't see a point to do that with 3 languages when I'm looking for a general language that can best help me for CS. I believe its C++, because it's still powerful, even after MS's deprecated language hallway. I guess I need confirmation?
