I mean the “official” or “traditional” alphabet, such as the one taught in schools to children. Is the ordering the same as English? Does it include ‘C’, which I notice never seems to show up in native-German words? Does it include ü, ö, ä, and ß? If so, where? Does that mean Germans think of the alphabet as having 30 letters? Or is it less than that with some of them considered variants?
It may seem like a silly question, but my wife was asking and I honestly don't know because I don't think I was ever taught these things in German class in college. I never thought about it at the time.
EDIT: To clarify, the question is: how do native Germans think about their alphabet? For example, Swedes drop ‘w’ from their alphabet and tack ‘å’, ‘ä’, and ‘ö’ onto the end. Spanish speakers consider ‘ñ’ (and, depending on who you ask, ‘ch’ and ‘ll’) to be different letters, but unlike the Swedes they have inserted these into the alphabet in dictionary order. They do not consider accented characters like é to be separate letters. Speaking from that context, how then do Germans think about their alphabet?
 Recognizing that there will be some variation between Germany, Austria, Switzerland, etc.
