The Differences Between C++ and C Sharp

Hash tables was one that eventually I got pretty deep into, but again, that's because it was in C. In C, you don't have a standard hash table facility. You mostly roll your own. Hash tables are really useful. But yeah, it's sort of a whole other world these days than it was then. Yeah. So my education was a long time back and there are a few things that are different from modern computer science. Did they go over hash tables significantly with you or dictionaries or any of the equivalent names for the same thing? If they did, I don't remember at all.
