In computer science, which place should corresponding author be listed?
In computer science, there is generally no straightforward connection between corresponding authorship and authorship order. There are even some fields, especially in Theoretical CS, where alphabetical ordering is the default. In other fields, seniority of authors (which is correlated to corresponding authorship, as the most senior author is usually most likely to keep his affiliation) can be a criterion for the ordering. But that's just one possible criterion among others (like, specifically, the amount of contribution).

In some conferences/journals, the corresponding author is explicitly highlighted in the author list (e.g., Springer LNCS series). In others (most IEEE/ACM-based ones), there is no explicit concept of corresponding author. The lead author (first author) can then be assumed to be the primary contact person.
