1. What is DirectX used for and how does it help in programming ?
2. What is Div Codec (or whatever it is called) ?
3. How many types of OS can C++ support ?

1. DirectX is a standard coding interface for programmers so they don't have to run around looking for hardware-specific stuff. DirectX gives you control of the hardware with standardized function calls and the like and doesn't make you have to write hardware-specific code. A lot of people dislike DirectX because it's based on Microsoft's old COM standard, which by all tokens absolutely blows for any sort of standard.
2. The DivX codec is a method of data compression. In order to make certain file types useable (video in raw format takes up ungodly amounts of space), people use file compression. DivX is a very good method of reusing old frame data in video to only store the essential stuff.
3. C++ works on any operating system it has a compiler for. This includes stuff you normally wouldn't consider, like internal car computers and electronics. Compilers translate source code into assembly code. An assembler than translates said code into a string of 0's and 1's that a machine can understand.
Hope it helps.

Couldn't have said it better myself. I'd like to add though, that DirectX is very commonly used for game developement, because of the fact that it is based on COM. It is very simple to impliment, and definately the fastest for windows (since Dx5.0 I believe it's been the fastest). As far as COM, I personally have always liked the idea...I'm actually looking forward to COM++...Just my 2 sense though  .

Phew, I just completed 3 Sessions from the C++ book which I bought
Too bad I don't have Visual C++ (Gonna get from friend) or any other compiler, otherwise I could try out a small pathetic program I just written
