Let me guess: Your using visual c++ 6 and some subpar textbook that uses outdated headers. The class is taught by some loser who is too stupid to get a real job actually programming. In fact judging by the time of year, you are on Chapter 2 which is titled "Graphics" or something of the sort. My advice: get a real c++ book, one that wasn't published in 1992. Don't expect to get anything out of this class.
