I'm gonna think on the several parts of "question 1", but "the other question" is easy...
The regex
/.*c/ will match the longest prefix that ends in c. So if fed "acrobatic cockatoos can fly", it would match "acrobatic cockatoos c". The regex
/[^c]*c/ would match the first prefix that ends in c, or "ac".
As far as
/.*?c/ goes... I think that is roughly equivilant to
/[^c]*c/, but I'm not positive.
