Several questions about the use of emacs

[Chen, Yukun]

Hi All
        Not sure whether anyone has the same experience. I have some questions 
about the usage of emacs as follows
        1. How can I comments a block of content once? (mean that I can comment 
sever lines by marking them with "//" at the start position in c language. I 
think it is useful in c development)
        2. Has emacs provided the function that complete the left character of 
a word, just as the commands of vi "ctrl + n" "ctrl + p" do?

        Thanx.
