As other people have said programming speed depends upon experience with a certain module, and the code you have laying around. Keeping a code base speeds things up drastically, so does using whatever code base you can that you know you can rely on, example: stl.

How long does it take to code something? Between 15 minutes and 2 days. Depending upon past experience with concepts the same as or similar to what is being done. Researching a new topic is very, very time expensive. Researching stuff in your off time, with attempted randomness or some measure of foresight; will save you hours when you're on the clock facing deadlines.

depends. what was it written in? c, assembly? win32, or some other low level API?

C# & Java are on higher levels, but their problem is that the layers cause you to learn
less and remember more, imo

C# with XNA. So its quite "high-level".
